Can't open and write an Excel file that should be created by MATLAB

5 views (last 30 days)
I have to write some large amount of data using xlswrite and since they are multiple files, they are written one by one . meaning that there is one xlswrite command for each matrix to be written.
after writing the first Excel file I get this error and matlab exists :
Warning: File not found or permission denied
> In xlswrite (line 223)
Warning: found error in 126976th line
Error: Excel Worksheet could not be activated.

sorry, the message has a problem, since I have created it through a request, it is 126976th line not file

I don't understand what that means, specifically. As requested, we need the full content of the error message and the code that generated it in context.
If you mean you have written a piece of code that duplicates xlswrite command 126,976 times plus, "Houston, we have a problem!" If that is the case you definitely need to look at how to write a generic loop construct instead.
