How to preserve matlab struct when accessing in python?

Question

I have a mat-file that I accessed using

from scipy import io
mat = io.loadmat(\'example.mat\')

From matlab, example.mat contains the following

Answer 1

(!) In case of nested structures saved in *.mat files, is necessary to check if the items in the dictionary that io.loadmat outputs are Matlab structures. For example if in Matlab

>> thisStruct

ans =
      var1: [1x1 struct]
      var2: 3.5

>> thisStruct.var1

ans =
      subvar1: [1x100 double]
      subvar2: [32x233 double]

Then use the code by mergen in scipy.io.loadmat nested structures (i.e. dictionaries)
