Matlab platform independent free memory

Matlab platform independent free memory

Related: free disk space check Matlab


Matlab’s built-in memory() command does not work on Linux or Mac.

  • check available RAM with Matlab or GNU Octave: memfree.m
  • check if an array can be created in RAM: checkRAM.m with Matlab or GNU Octave.

For Matlab ≥ R2015a, the option Preferences > MATLAB > Workspace > Matlab array size limit attempts to stop the user from creating arrays that dig into swap memory (extremely slow).
