I'm trying to solve a set of equations of motion of a system by ode45 in Matlab.
My phyisical memory is 24 GB. Matlab can use up to 100% of the memory but it only uses less than 50% of it and surprisingly I face an 'Out of memory' error!
What do you suggest as the cause of this problem?
Try to increase "Matlab array size limit" that you can find in Preferences -> Matlab -> Workspace.
Check the Matlab website
https://www.mathworks.com/help/matlab/matlab_prog/resolving-out-of-memory-errors.html
for 5-6 different approaches for resolving such issue.
Btw, keep in mind that:
"If you turn off the array size limit in MATLAB Workspace Preferences, attempting to create an unreasonably large array might cause MATLAB to run out of memory, or it might make MATLAB or even your computer unresponsive due to excessive memory paging (that is, moving memory pages between RAM and disk)."
I think the problem lies in MATLAB's attempts to create an array larger than the "maximum possible array". This error does not depend on the "memory used by MATLAB". You should check your script and fix it to prevent creating of too large arrays.
Dear Alessandro di Gaeta
Thanks for your response.
It's already on the maximum limit.
In the new run of my code, I got these numbers for memory usage:
