When I run the following code
function feff
filename = 'UHL DEA.xlsx';
FI = xlsread(filename,'AU9:AU179');
FO = xlsread(filename,'AW9:AW179');
FEff = FI./FO;
%Write the efficiency back to the appropriate file in excel
xlswrite(filename,FEff,'BC9:BC179');
I get the error
Error using xlswrite (line 220)
Excel returned: Error: Object returned error code: 0x800A03EC.
Error in feff (line 15)
xlswrite(filename,FEff,'BC9:BC179');
But it works fine if i write into another file as follows
function feff
filename = 'UHL DEA.xlsx';
FI = xlsread(filename,'AU9:AU179');
FO = xlsread(filename,'AW9:AW179');
FEff = FI./FO;
%Write the efficiency back to the appropriate file in excel
xlswrite('DEA.xlsx',FEff,'BC9:BC179');
The UHL DEA.xlsx contains other data in the previous columns and I need to write this data again in the same file. Pointers will be appreciated. Thanks
Are you using a backward compatible xls file?
HRESULT: 0x800A03EC on Worksheet.range
Check the accepted answer.
Edit: If this is not it, what happens if you try to edit the entire range without using matlab?

I'm reading a dat file using textread.
the code works fine on the Matlab in windows, but shows an error in linux:
input_file = "/home/ec2-user/mydat.dat";
[a,b,c,d,e,g,h,i] = textread(input_file,'%s%s%d%d%f%f%f%f%*f%*f%*f%*f','delimiter',',');
The error is as bellow:
Error using fullfile (line 51)
String input not supported.
Error in textread (line 151)
if (noargname(#exist,varargin{1}) ~= 2 || noargname(#exist,fullfile(cd,varargin{1})) ~= 2)
Changing "textread" to "txtscan" shows another error:
Error using textscan
Too many output arguments.
changing to:
res_txtscan = textscan(input_file,'%s%s%d%d%f%f%f%f%*f%*f%*f%*f','delimiter',',');
a = res_txtscan{1}
the result is:
a =
0×1 empty cell array
and same result for b~i
The version of Matlab on Windows is R2014a and on Linux: 20107a.
I'm having trouble printing a table to a file with lua (and I'm new to lua).
Here's some code I found here to print the table;
function print_r ( t )
local print_r_cache={}
local function sub_print_r(t,indent)
if (print_r_cache[tostring(t)]) then
print(indent.."*"..tostring(t))
else
print_r_cache[tostring(t)]=true
if (type(t)=="table") then
for pos,val in pairs(t) do
if (type(val)=="table") then
print(indent.."["..pos.."] => "..tostring(t).." {")
sub_print_r(val,indent..string.rep(" ",string.len(pos)+8))
print(indent..string.rep(" ",string.len(pos)+6).."}")
elseif (type(val)=="string") then
print(indent.."["..pos..'] => "'..val..'"')
else
print(indent.."["..pos.."] => "..tostring(val))
end
end
else
print(indent..tostring(t))
end
end
end
if (type(t)=="table") then
print(tostring(t).." {")
sub_print_r(t," ")
print("}")
else
sub_print_r(t," ")
end
print()
end
I have no idea where the 'print' command goes to, I'm running this lua code from within another program. What I would like to do is save the table to a .txt file. Here's what I've tried;
function savetxt ( t )
local file = assert(io.open("C:\temp\test.txt", "w"))
file:write(t)
file:close()
end
Then in the print-r function I've changed everywhere it says 'print' to 'savetxt'. This doesn't work. It doesn't seem to access the text file in any way. Can anyone suggest an alternative method?
I have a suspicion that this line is the problem;
local file = assert(io.open("C:\temp\test.txt", "w"))
Update;
I have tried the edit suggested by Diego Pino but still no success. I run this lua script from another program (for which I don't have the source), so I'm not sure where the default directory of the output file might be (is there a method to get this programatically?). Is is possible that since this is called from another program there's something blocking the output?
Update #2;
It seems like the problem is with this line:
local file = assert(io.open("C:\test\test2.txt", "w"))
I've tried changing it "C:\temp\test2.text", but that didn't work. I'm pretty confident it's an error at this point. If I comment out any line after this (but leave this line in) then it still fails, if I comment out this line (and any following 'file' lines) then the code runs. What could be causing this error?
I have no idea where the 'print' command goes to,
print() output goes to default output file, you can change that with io.output([file]), see Lua manuals for details on querying and changing default output.
where do files get created if I don't specify the directory
Typically it will land in current working directory.
Your print_r function prints out a table to stdout. What you want is to print out the output of print_r to a file. Change the print_r function so instead of printing to stdout, it prints out to a file descriptor. Perhaps the easiest way to do that is to pass a file descriptor to print_r and overwrite the print function:
function print_r (t, fd)
fd = fd or io.stdout
local function print(str)
str = str or ""
fd:write(str.."\n")
end
...
end
The rest of the print_r doesn't need any change.
Later in savetxt call print_r to print the table to a file.
function savetxt (t)
local file = assert(io.open("C:\temp\test.txt", "w"))
print_r(t, file)
file:close()
end
require("json")
result = {
["ip"]="192.168.0.177",
["date"]="2018-1-21",
}
local test = assert(io.open("/tmp/abc.txt", "w"))
result = json.encode(result)
test:write(result)
test:close()
local test = io.open("/tmp/abc.txt", "r")
local readjson= test:read("*a")
local table =json.decode(readjson)
test:close()
print("ip: " .. table["ip"])
2.Another way：
http://lua-users.org/wiki/SaveTableToFile
Save Table to File
function table.save( tbl,filename )
Load Table from File
function table.load( sfile )
I have a problem with a corrupted excel file. So far I have used 7zip to open it as an archive and extract most of the data. But some important sheets cannot be extracted.
Using the l command of 7zip I get the following output :
7z.exe l -slt "C:\Users\corrupted1.xlsm" xl/worksheets/sheet3.xml
Output:

However when trying to extract it (or test it for that matter) I get :
7z.exe t -slt "C:\Users\corrupted1.xlsm" xl/worksheets/sheet3.xml
Output:
Processing archive: C:\Users\corrupted1.xlsm

The method listed above says Deflate, which is the same for all the worksheets.
Is there anything I can do? What kind of corruption is this? Is it the CRC? Can I ignore it somehow or something?
Please help!
Edit:
The following is the error when trying to extract or edit the xml file through 7zip:
Edit 2:
Tried with WinZip as well, getting :

I am trying to find the data between two values. I am using this code in a GUI programme, the starting_value and ending_value which you can see in the code below are selected from 2 listboxes in a previous part of the code.
% --- Executes on button press in CalculateIntensity.
function CalculateIntensity_Callback(hObject, eventdata, handles)
% hObject handle to CalculateIntensity (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
% Trapz function
starting_value = getappdata(0,'StartValue');
ending_value = getappdata(0,'EndValue');
StartingValue = str2mat(starting_value)
EndingValue = str2mat(ending_value)
A = getappdata(0,'XYarray')
data_found = A(A(:,[1,2]) > StartingValue & A(:,[1,2]) < EndingValue)
I found help on:
http://www.mathworks.com/matlabcentral/answers/8556-how-to-find-vector-elements-between-two-values-efficiently
However the
data_found = A(A(:,[1,2]) > StartingValue & A(:,[1,2]) < EndingValue)
part of the code wont work for me, I think starting_value and ending_value are strings so I tried converting it to a matrix but I get the error:
Error using <
Matrix dimensions must agree.
Error in MichelleLaycockGUImainwindow>CalculateIntensity_Callback (line 119)

I'm not really sure where I'm going wrong, any help would be greatly appreciated as it's all I need to complete my work. Thanks in advance!
As some of the values in my data vary rather than just decreasing or increasing the greater than or equal to method I was originally trying to use did not work. So rather than using the loop to get the data between the two points selected I went with a different method.
I use[~,indx1]=ismember(StartingValue,A,'rows') this finds the row number of the selected data and then I use this information to extract the data between and including the selected data.
Here is the full code I used to do this:
starting_value = getappdata(0,'StartValue');
ending_value = getappdata(0,'EndValue');
StartingValue = str2num(starting_value);
EndingValue = str2num(ending_value);
A = getappdata(0,'XYarray');
[~,indx1]=ismember(StartingValue,A,'rows');
[~,indx2]=ismember(EndingValue,A,'rows');
arrayfortrapz = A(indx1:indx2,1:2); %array of data including and between selected data
I hope this of some help to anybody that may run into a similar issue.
I am using MatlabR2011a on my Windows 7 machine.
I have a folder of 635 text files. Each file contains multiple rows and 2 columns. I am trying to loop through the folder and read each file and write these values to excel. So far this is what I have:
close all; clc;
dirname = uigetdir;
Files = dir(fullfile(dirname,'*.txt'))
for k = 1:635
j =1
filename = fullfile(dirname,Files(k).name);
fid = fopen(filename);
x = fgetl(fid)
while ischar(x)
x = fgetl(fid)
a2 = strtrim(x);
a3 = textscan(a2,'%s');
a4 = a3{1}{1};
a5= a3{1}{2};
pos3 = strcat('A',num2str(j));
xlswrite('sample_output',{a4,a5},'Sheet1',pos3)
j = j+1;
end
fclose(fid);
end
It keeps giving me the following error after finishing reading the first file.
Error using ==> strtrim Input should be a string or a cell array of strings.
A sample input file looks like this:
15076 4636259
15707 4636299

15721 4204950

How can I fix this? Would appreciate help with this!
In the while loop, cut the line
x=fgetl(fid)
...and paste it before the end statement right after j=j+1.
The error occurs because you get a line before the while statement, then you use the while statement to test validity of the string (all fine so far), but then immediately get the subsequent line before you perform your string operation. The call to fgetl at the start of the while block could return an EOF, causing subsequent string manipulation functions to fail.
Also... The code would be more robust if you set your for loop like so
for k=1:numel(Files)
Since all your data are numeric this should work. Give it a try.
dirname = uigetdir;
Files = dir(fullfile(dirname,'*.txt'))
j =0;
for k = 1:numel(Files)
filename = fullfile(dirname,Files(k).name);
x = dlmread(filename,'\t'); %# I assume tab-delimiter
j = j + size(x, 1);
xlswrite( 'sample_output', x, 'Sheet1',sprintf('A%d',j) )
end
