I have a ".mat" file that I want to open and see the contents of. Since I don't have MATLAB, I downloaded GNU's Octave. Since I'm working on Mac's TERMINAL, I'm not exactly sure how to open the ".mat" file so that I can see the contents. Can anyone help me with this? Thanks!
Not sure which version of .mat file you might have, or whether Octave keeps up with the latest Matlab formats.
Here's a link that might be a good start.
Bottom line is that you can say: load MyMatFile.mat right at the Octave prompt.
In case you wind up having to write code to read the .mat file ever: I've done this before and it was not difficult, but was time-consuming. Mat file format for 2012a
If your file contains only numbers, no .mat header, then this should work:
variable = load("filename")
