Hello all,

I made an m-file which runs a lot of external executables through the dos command within a for loop as follows: [~,~]=dos(code);

Mostly this works perfectly. However, sometimes the external executable crashes and gives a Windows error as shown below. I don't really care about this error, I just want to close it and continue processing the m-file. Currently I have to manually close the error and then the m-file automatically continues, but I want to have the m-file run independently for multiple hours, so manual input is undesired. Is there anybody who can assist me with this question?

Thanks in advance for any help.

I wonder if you would be able to improve on the situation by using .NET System.Diagnostics.Process instead of calling dos() ? https://www.mathworks.com/matlabcentral/answers/575608-system-and-system-diagnostics-process#answer_485447

Hello @Riccardo Albertin,

Thanks for asking. Unfortunately, back then I wasn't able to actually suppress the error message. I think I changed the input to the executable so that it didn't crash. Which probably in general is a better solution, but that might not be viable in your situation.

Additionally, I changed the entire m-file (an application now) to Python, which I think is a bit more suited for running external executables.

Good luck!
