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.
