I wrote a small function that transforms the dictionary into a cell array and then that cell array is used to populate a structure. Same principle can be applied to other python dictionaries. Hope this somehow works for anyone else working with Matlab and Python.
function new_s=my_py2mat(a,b,c)
n=py.py2mat.test(a,b,c);
s=struct(n);
field_list=fieldnames(s);
rows=double(py.len(s.(field_list{1}))); %size and numel can't acquire the dimension of a python dictionary, that's why we call py.len()
new_array=cell(rows,numel(field_list));
for i=1:numel(field_list)
temp=s.(field_list{i});
for j=1:rows
if isa(temp{j-1},'py.str')
new_array{j,i}=char(temp{j-1});
elseif isa(temp{j-1},'py.int')
new_array{j,i}=double(temp{j-1});
else
new_array{j,i}=temp{j-1};
end
end
s.(field_list{i})=new_array(:,i);
end
new_s=s;
