编辑： Torsten 2024-2-23

I am running Matlab 2013b.

I have a function that analyzes data. It runs correctly when executed within Jenkins running on Linux. The code takes about an hour to run.

When I run on my Windows PC in a Putty window connected to a Linux box Matlab crashes every time. It crashes when executing the line "var = randperm(N)", where N is a double with a value = 58. I stepped through the code manually and stopped at different points and typed "var = randperm(58)" without any problem. This problem was verified by a second engineer who had run across the same problem weeks before me.

I have no idea how to troubleshoot this problem.

Thanks in advance for any help.

Mike

Jeff, the following works fine

idx = 1:length(X);

Walter,

which -all randperm

yields the following

built-in (/apps/MATLAB/R2013b/toolbox/matlab/randfun/randperm)

/apps/MATLAB/R2013b/toolbox/matlab/randfun/@RandStream/randperm.mexa64 % RandStream method

/apps/MATLAB/R2013b/toolbox/matlab/randfun/@RandStream/randperm.m % RandStream method

David,

I agree with your use of size over length, but, this is code that has been developed over years that I am now making changes to. I always tread lightly when I am the new guy.

Thank you all for your time.
