[Paraview] reading MATLAB file

[Heiland, Randy]

Not sure, but think it’s irrelevant for my particular use. I'm going to try the Programmable Source (Python script) approach (and use scipy.io.loadmat to read my .mat file). Maybe I missed it - is there a way to read in this script from a file? (copy/pasting into the Pgmable Source widget certainly works; just asking)  Thanks!

In the past, I’ve manually converted the files into .vtk formats using Python w/ scipy to load/parse the .mat files. But I’d like to avoid creating additional files and just read the .mat files directly.
