I am working with 3 functions running in parallel with parfor, and they are supposed to give approximately 3000 output files each. The code doesn't change much between each iteration, they are basically 3 big loops.
However, they stop running after around 250 iterations and I have this error message on one of them:
Error using xlsread (line 257)
Invoke Error, Dispatch Exception:
Source: Microsoft Excel
Description: Open method of Workbooks class failed
Help File: xlmain11.chm
Help Context ID: 0
Error in read_excel2cell (line 2)
[dummy1, dummy2, result] = xlsread(filename);
I tried restarting Matlab, restarting my pc, overwriting the .xlsx files in case they were corrupted etc... But I can't get it work while the exact same code was working fine this morning.
Does anybody have a lead on what could cause this kind of issue ? I exhausted every solution I could find about it.
Have a nice day
