problem related to GUI

Hi, I'm Chang.

Recently, I am making a gui for ANN.

to make a GUI, I want to load a mat file saved the learning result of ANN using pushbutton.

but when I tried to do that, I couldn't do anything.

please let me know How can I load the mat file.

additionally, I want to know when I implement command 'sim', the button to simulate ANN, whether it is worked or not.

I hope you guys help me. thank you.

"I couldn't do anything" does not allow to suggest an improvement. Loading the MAT files works by load(FileName), but this seems to be obvious. Please post the relevant part of the code and explain the occurring problems with details.
