MATLAB: How to load a mat.file from a selected folder to workspace from a GUI and MAINTAIN the original Data Type

.mat fileguiloadstructworkspace

Hello,
i found this code snippet for loading a mat.file to the workspace. It works fine! The only problem is, that the file is a STRUCT!!!
When i open the file manually from the matlab surface, it is a Matrix named 'x'. Thats how i would like it to be here tooo! dont want to have a struct instead.
startingFolder = 'C:\Program Files\MATLAB'
    % Get the name of the mat file that the user wants to use.
        defaultFileName = fullfile(startingFolder, '*.mat')
        [baseFileName, folder] = uigetfile(defaultFileName, 'Select a mat file')
        if baseFileName == 0
            % User clicked the Cancel button.
            return;
        end
        fullFileName = fullfile(folder, baseFileName)
        storedStructure = load(fullFileName)  % only available in the GUI so far, not in the workspace 
        assignin('base', 'storedStructure', storedStructure); % now transported to the workspace, accessable by storedStructure.x
Can anybody help me with that plz:)
thank you very much!
Best regards, John

Best Answer

assignin('base', 'x', storedStructure.x); % now transported to the workspace
However, this is not recommended!
