I am trying to figure out how to specify a common range for xlsread() function in matlab.
Usually I use n=xlsread('filename','#sheet','A1:A10'), but I have quite a bit of data in the same sheet and I'd like to know if I can specify it with one range, i.e . if all my data is between '1:10', I want to specify 1:10 as range, and only call the letter values of each column.
I was thinking to do it as follows:
function [a,b,c]=getdata(filename,'1:10')
a=xlsread(filename,1,'A:A'???)
b=xlsread(filename,1,'B:B'???)
c=xlsread(filename,1,'C:C'???)
end
After some research I could not find any information as to how this is done.
Thanks in advance,
Greg
If you want to read 1 to 10 rows of column A, use:
data = xlsread(filename, 1, 'A1:A10');
If you want to read 1 to 10 rows of all columns, use:
data = xlsread(filename, 1, '1:10');
If you want to read 1 to 10 rows of, say, first three columns A, B, and C, use:
data = xlsread(filename, 1, 'A1:C10');
Using dynamic variable names is always a bad idea. Read this for explanation. But if you still want to create a, b, and c and so on depending on the number of columns in the Excel file, you can use:
for k=1:size(data,2)
assignin('caller', char(96+k), data(:,k)); %or char(64+k) for block letters
end
The above will work if number of columns are less than or equal to 26. This may only be feasible if you're dealing with a few columns. But I still recommend to avoid it.

In my Excel file, I have data split up over different tables for different values of parameter X.
I have tables for parameter X for values 0.1, 0.5, 1, 5 and 10. Each table has a parameter Y at the far left that I want to able to search for with a few data cells right of it. Like so:
X = 0.1
Y
Data_0
Data_1
Data_2
1
0.071251
0.681281
0.238509
2
0.283393
0.509497
0.397196
3
0.678296
0.789879
0.439004
4
0.788525
0.363215
0.248953
etc.
Now I want to find Data_0, Data_1 and Data_2 for a given X and Y value (in two separate cells).
My thought was naming the tables X0.1 X0.5 etc. and when defining the matrix for the lookup function use some syntax that would change the table it searches in. With three of these functions in adjacent cells, I would obtain the three values desired.
Is that possible, or is there some other method that would give me the result I want?
Thanks in advance
On the question what would be my desired result from this data:
I would like A1 to give the value for the X I'm searching for (so 0.1 in this case)
A2 would be the value of Y (let's pick 3)
then I want C1:E1 to give the values 0.678... 0.789... 0.439...
Now from usmanhaq, I think it should be something like:
=vlookup(A2,concatenate("X",A1),2)
=vlookup(A2,concatenate("X",A1),3)
=vlookup(A2,concatenate("X",A1),4)
for the three cells.
This exact formulation doesn't work and I can't find the formulation that does work.
I understand the question is confusing, so I got a self explanatory picture for you.
I've got a long column with repeating cells in sets of 3, rarely 2. To be precise, it's in the format of A-1, A-2, A-3, B-1, B-2, B-3, and so on.
The part after the hyphen is always the same, but the part before varies.
A and B will each have 3 elements, then C will look like C-1, C-2 with no C-3.
It doesn't happen often in the column but it does sometimes.
Now I have to take all 3 elements of A and spread them into 3 separate columns just like in the picture. Is this doable in sheets/excel?
GS:
=ARRAYFORMULA(IFNA(VLOOKUP({FILTER(A2:A, REGEXMATCH(A2:A, "-1$")),
FILTER(REGEXEXTRACT(A2:A, "(.+-)")&2, REGEXMATCH(A2:A, "-1$")),
FILTER(REGEXEXTRACT(A2:A, "(.+-)")&3, REGEXMATCH(A2:A, "-1$"))}, A2:A, 1, 0)))
Here is a version Excel Office365 version. It lists out all the .pdf options in the header since it looks like you have alternate spellings in the file names.
=LET(input,A2:A1000,
data,FILTER(input,(input<>"")*(RIGHT(input,4)=".pdf")),
rightPartDash,IF(ISERROR(FIND("-",data)),data, RIGHT(data,LEN(data) - FIND("|",SUBSTITUTE(data,"-","|",LEN(data)-LEN(SUBSTITUTE(data,"-","")))))),
rightPartSpace,IF(ISERROR(FIND(" ",data)),data, RIGHT(data,LEN(data) - FIND("|",SUBSTITUTE(data," ","|",LEN(data)-LEN(SUBSTITUTE(data," ","")))))),
rightpart,IF(LEN(rightPartSpace)>LEN(rightPartDash),rightPartDash,rightPartSpace),
leftPart,LEFT(data,LEN(data)-LEN(rightpart)),
leftList,UNIQUE(leftPart),
rightList,TRANSPOSE(UNIQUE(rightpart)),
searchFor,leftList&rightList,
output, XLOOKUP(searchFor,data,data,""),
i, SEQUENCE(ROWS(leftList)+1,1,0),
j, SEQUENCE(1,COLUMNS(rightList)),
IF(i = 0,rightList,INDEX(output,i,j)))
everyone...
I just started on python a couple of days ago because I require to handle some excel data in order to automatically update the data of certain cells from one file into another.
However, I'm kind of stuck since I have barely programmed before, and it's my first time using python as well, but my job required me to find a solution and I'm trying to make it work even though it's not my field of expertise.
I used the "xlrd library", imported my file and managed to print the columns I'm needing... However, I can't find a way to put those columns into a matrix in order to handle the data like this:
Matrix =[DataColumnA DataColumnG DataColumnH] in the size [nrows x 3]
As for now, I have 3 different outputs for the 3 different columns I need, but I'm trying to join them together into one big matrix.
So far my code looks like this:
import xlrd
workbook = xlrd.open_workbook("190219_serviciosWRAmanualV5.xls");
worksheet = workbook.sheet_by_name("ServiciosDWDM");
workbook2 = xlrd.open_workbook("Potencia2.xlsx");
worksheet2 = workbook2.sheet_by_name("Hoja1");
filas = worksheet.nrows
filas2 = worksheet2.nrows
columnas = worksheet.ncols
for row in range (2, filas):
Equipo_A = worksheet.cell(row,12).value
Client_A = worksheet.cell(row,13).value
Line_A = worksheet.cell(row, 14).value
print (Equipo_A, Line_A, Client_A)
So I have only gotten, as mentioned above, the data in the columns which is what I'm printing which you can see.
What I'm trying to do, or the main thing I need to do is to read the cell of the first row in Column A and look for it in the other excel file... if the names match, I would have to validate that for the same row (in file 1) the data in both the ColumnG and ColumnH is the same as the data in the second file.
If they match I would have to update Column J in the first file with the data from the second file.
My other approach is to retrieve the value of the cell in ColumnA and look for it in the column A of the second file, then I would make an if conditional to see if ColumnsG and H are equal to Column C of 2nd file and so on...
The thing here is, I have no idea how to pin point the position of the cell and extract the data to make the conditional for this second approach.
I'm not sure if by making that matrix my approach is okay or if the second way is better, so any suggestion would be absolutely appreciated.
Thank you in advance!
This question relates to the Schematiq add-in for Microsoft Excel.
Using =tbl.Lookup(table, columnsToSearch, valuesToFind, resultColumn, [defaultValue]) the values in the valuesToFind column have a consistent 3 characters to the left and then varying characters after (e.g. 908-123456 or 908-321654 - i.e. 908 is always consistent)
How can I tell the function to lookup the value based on the first 3 characters only? The expected answer should be the sum of the results of the above, i.e. 500 + 300 = 800
tbl.Lookup() works by looking for an exact match - this helps ensure it's fast but in this case it means you need an extra step to calculate a column of lookup values, something like this:
A2: =tbl.CalculateColumn(A1, "code", "x => LEFT(x, 3)", "startOfCode")
This will give you a new column that you can use for the columnsToSearch argument, however tbl.Lookup() also looks for just one match - it doesn't know how to combine values together if there is more than one matching row in the table, so I think you also need one more step to group your table by the first 3 chars of the code, like this:
A3: =tbl.Group(A2, "startOfCode", "amount")
Because tbl.Group() adds values together by default, this will give you a table with a row for each distinct value of startOfCode and the subtotal of amount for each of those values. Finally, you can do the lookup exactly as you requested, which for your input table will return 800:
A4: =tbl.Lookup(A3, "startOfCode", "908", "amount")
I need to be able to search my whole table for a row that matches multiple criteria. We use a program that outputs data in the form of a .csv file. It has rows that separate sets of data, each of these headers don't have any columns that are unique in of them self but if i searched the table for multiple values i should be able to pinpoint each header row. I know i can use Application.WorksheetFunction.Match to return a row on a single criteria but i need to search on two three or four criteria.
In pseudo-code it would be something like this:
Return row number were column A = bill & column B = Woods & column C = some other data
We need to work with arrays:
There are 2 kinds of arrays:
numeric {1,0,1,1,1,0,0,1}
boolean {TRUE,FALSE,TRUE,TRUE,TRUE,FALSE,FALSE,TRUE}
to convert between them we can use:
MATCH function
MATCH(1,{1,0,1,1,1,0,0,1},0) -> will result {TRUE,FALSE,TRUE,TRUE,TRUE,FALSE,FALSE,TRUE}
simple multiplication
{TRUE,FALSE,TRUE,TRUE,TRUE,FALSE,FALSE,TRUE}*{TRUE,FALSE,TRUE,TRUE,TRUE,FALSE,FALSE,TRUE} -> will result {1,0,1,1,1,0,0,1}
you can can check an array in the match function, entering it like in the picture below, be warned that MATCH function WILL TREAT AN ARRAY AS AN "OR" FUNCTION (one match will result in true
ie:
MATCH(1,{1,0,1,1,1,0,0,1},0)=TRUE
, YOU MUST CTR+SHIFT+ENTER !!! FOR IT TO GIVE AN ARRAY BACK!!!
in the example below i show that i want to sum the hours of all the employees except the admin per case
we have 2 options, the long simple way, the complicated fast way:
long simple way
D2=SUMPRODUCT(C2:C9,(A2=A2:A9)*("admin"<>B2:B9)) <<- SUMPRODUCT makes a multiplication
basically A1={2,3,11,3,2,4,5,6}*{0,1,1,0,0,0,0,0} (IT MUST BE A NUMERIC ARRAY TO THE RIGHT IN SUMPRODUCT!!!)
ie: A1=2*0+3*1+11*1+3*0+2*0+4*0+5*0+6*0
this causes a problem because if you drag the cell to autocomplete the rest of the cells, it will edit the lower and higher values of
ie: D9=SUMPRODUCT(C9:C16,(A9=A9:A16)*("admin"<>B9:B16)), which is out of bounds
same as the above if you have a table and want to view the results in a diferent order
the fast complicated way
D3=SUMPRODUCT(INDIRECT("c2:c9"),(A3=INDIRECT("a2:a9"))*("admin"<>INDIRECT("b2:b9")))
it's the same, except that INDIRECT was used on the cells that we want not be modified when autocompleting or table reorderings
be warned that INDIRECT sometimes give VOLATILE ERROR,i recommend not using it on a single cell or using it only once in an array
f* c* i cant post pictures :(
table is:
case emplyee hours totalHoursPerCaseWithoutAdmin
1 admin 2 14
1 him 3 14
1 her 11 14
2 him 3 5
2 her 2 5
3 you 4 10
3 admin 5 10
3 her 6 10
and for the functions to check the arrays, open the insert function button (it looks like and fx) then doubleclick MATCH and then if you enter inside the Lookup_array a value like
A2=A2:A9 for our example it will give {TRUE,TRUE,TRUE,FALSE,FALSE,FALSE,FALSE,FALSE} that is because only the first 3 lines are from case=1
Something like this?
Assuming that you data in in A1:C20
I am looking for "Bill" in A, "Woods" in B and "some other data" in C
Change as applicable
=IF(INDEX(A1:A20,MATCH("Bill",A1:A20,0),1)="Bill",IF(INDEX(B1:B20,MATCH("Woods",B1:B20,0),1)="Woods",IF(INDEX(C1:C20,MATCH("some other data",C1:C20,0),1)="some other data",MATCH("Bill",A1:A20,0),"Not Found")))
SNAPSHOT
I would use this array* formula (for three criteria):
=MATCH(1,((Range1=Criterion1)*(Range2=Criterion2)*(Range3=Criterion3)),0)
*commit with Ctrl+Shift+Enter
