I make a GUI and I want to add a push button that will load a m-file.

Please explain further what you mean by "load" of an m file. Do you mean execute the file, or do you mean upload from somewhere to somewhere else?

I want to do something like this: upload data from m-file to workspace and then my Simulink simulation will downaload this data to run a simulation with this parameters.

under the callback of the button in the code of that gui, put something like this:
evalin('base','<your_m_file>')
This will run the m-file and load the variables in the matlab workspace! So not in the GUI workspace. If you want to have the variables in the local workspace of the GUI you can use, after the callback is finished the GUI workspace is deleted, so if you want to keep the values of the mfile in the GUI accessible you have to save them in the global structure (the handles structure by default):
eval('<your_m_file>')
also do not include the .m extension in the name.

If I understand you correctly, it seems to me that you start the simulink simulation from the m-file, right ? If the m-file is run by the code in the gui, i suppose that the mistake is in the m-file itself. It could be that you use the wrong command to start the simulation. Try using sim() instead of open() or run(). For better help, you should upload the part of the code that currently does this, or give me some more information on what happens and what you would expect to happen.
