function dat = dspace2struct(filename,version,alternative_struct_name)
% ------------------------------------------------
% dat = dspace2struct(dspacename,version)
% Function to export dSPACE-mat-file to Matlab struct.
% The fieldnames of the struct are the same as the dSPACE-signalnames.
% ------------------------------------------------
% Output:
% dat ... matlab struct
%
% Input:
% filename ... (optional) .mat-File generated by dSPACE (string) (
% version ... (optional) version = 'NG' if using dSpace Next Genertion
% alternative_struct_name ...(optional) needed if structname is different
% from filename. Often caused by renaming .mat
% files after saving.
