How to add path to block From multimedia file, from Matlab workspace

Hi,

I would like to add path to simulink simulation controlled by Matlab GUI. I wrote a code which get path to the file:

function browse_button_Callback(hObject, eventdata, handles)

[filename,filepath] = uigetfile({'*.mp3';'*.wav';'*.*'}, 'Search sound file to process');

fullname = [filepath filename];

But I cannot assign any variable to catch from workspace:

So I cannot write:

assignin("base","fullname",file);

In order to set this in parameters of .slx.

Is there any way code this path?

To assign the value of "fullname" to a variable called 'file' in the base workspace, it needs to be:

assignin('base','file',fullname)

But still, this won't work as you expected.

You could do

fullname=fullfile(filepath,filename)
set_param(ThisFromMultimediumBlockPath, 'inputFilename',fullname)
