I am trying to fill a column in Excel with values that are generated randomly but the sum of all the values total to the end.
Example:
Starting value = 320
Final value = 350
Need to generate 2 more values which have random difference between them but total to 350 at the end, as in: 2nd val = 12, 3rd val = 18.
The script/formula should generate different values when run next (for another table etc.). It may generate, for the same starting and final values, 15 and 15 or 8 and 22 for the 2nd and 3rd values respectively etc.
Basically what the formula should do is: Find the difference between the starting and final values then randomly add a number to create the 2nd entry. Now the third entry should follow the same pattern but the value generated should end up totaling to the final.
The example is only for 2 values but I'm working on tables ranging from 15-30+ values.
I don't know if Excel can do it, or if there's a mathematical formula that will work here.
Thanks in advance for all the help!
You need something like this:
That gives:
The trick is to generate a list of uniform random numbers between 0 and 1 and then scale those numbers up the total that you're looking for.
Following from the example here I'm trying to add additional conditions to a sum formula. I've represented an example below:
The output that I'm looking for for example for Jan 2017 is
2017
1
UP A 1
UP B 6
UP C 6
DOWN A 1
DOWN B 8
DOWN C 7
I tried with the following formula:
=MMULT(--($B$17:$C$17="X"),MATCH(1,($A23=$C$2:$C$14)*(C$21=$A$2:$A$14)*(C$22=$B$2:$B$14)*($E$2:$E$14=$D$2:$D$14),0))
but I get a N/A value.
Does anyone know it if is possible to do it?
In your first example the number of rows in array1 and number of columns in array2 were equal, five. Here you have two columns and 13 rows. That they are unequal here is part (all) of the reason why you are having an issue.
Also your match function is returning a Boolean not an array
I have a way to do this using matrix condition and multiple criteria but had to change problem up a bit, see photo for example:
{=MMULT(--(D18:P18="x"),E$2:E$14*(--(A$2:A$14=$C$21)*--(B$2:B$14=$C$22)*--(C$2:C$14=A24)))"

You can create a formula to fill the second matrix with X's see below
=IF(OR(INDIRECT("D"&VALUE(D20))=$A$18,INDIRECT("D"&VALUE(D20))=$B$18),"X","")
https://i.stack.imgur.com/4rS4L.png
That being said I don't think this is particularly efficient as you are treating the one of the matrixes as a all 1's so you basically just adding an extra criteria / Boolean with added complexity....that being said u asked for this specifically and I believe that I have delivered that LOL
Just add two SUMIFS together.
=SUMIFS($E$2:$E$14, $A$2:$A$14, C$21, $B$2:$B$14, C$22, $C$2:$C$14, $A23, $D$2:$D$14, IF(INDEX($B$17:$C$19, MATCH($B23, $A$17:$A$19, 0), 1)="x", $B$16))+
SUMIFS($E$2:$E$14, $A$2:$A$14, C$21, $B$2:$B$14, C$22, $C$2:$C$14, $A23, $D$2:$D$14, IF(INDEX($B$17:$C$19, MATCH($B23, $A$17:$A$19, 0), 2)="x", $C$16))
I have sets of gene probes that are upregulated when put under different chemical stresses. Each column contains all of the upregulated gene probes. I have 12 columns, how do I get a list of gene probes that appear in all 12 columns?
I've been able to find similarities between two columns using the formula
=IF(ISERROR(MATCH(A2,$C$2:$C$21473,0)),"",A2)
but cant work out how to adapt it to include 12 columns

Heres the first 8 rows of the 12 columns. There are 21473 rows in total.
Thanks
You could use an array formula like this to count how many columns a particular gene probe occurs in
=SUM(--(MMULT(TRANSPOSE(ROW(A$2:L$10000)^0),N(A$2:L$10000=A2))>0))
This is a standard way of getting column totals for a 2D array - in this case an array of true/false values corresponding to instances of an array element being equal/unequal to A2.
It is rather a brute force approach - it needs ~120K multiplications for each row. If you copy the formula down for ~10K rows, there is a delay of ~100 seconds on my computer while Excel works out the results.
Must be entered as an array formula using CtrlShiftEnter
In this dummy data C is the only value that occurs in all 12 columns.
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
