I recently upgraded to 2016a. Now, when I load .mat files save with 2014b, it takes several minutes for them to load. Any idea how I can speed this up? Thanks!

Hello,

The version that the .MAT file is saved in does influence the performance. Refer to documentation @George mentioned in his comment: https://www.mathworks.com/help/matlab/import_export/mat-file-versions.html

One way to improve performance is to use the "matfile" function. This will allow you to load certain variables that you need without loading the entire file into memory.

For more information see the following documentation: https://www.mathworks.com/help/matlab/ref/matfile.html
