Why can't I save this structure as a .mat file?

I'm trying to save a structure with several fields in matlab. The following lines save the data to the desired folder:

filename_output = [outpath subf(k).name '_timeseries.mat'];
save(filename_output,'-struct','my_structure');

But when I try to load the structure with:

 load(filename_output)

I get a bunch of separate variables, not in a structure. Am I overlooking something?

You did not save a structure. The '-struct' option splits the fields of my_structure into separate variables before saving. However, it is best practice anyway to call load() with an output argument,

myStruct = load(filename_output)

and when you do you obtain your variables again in structure form.
