You forgot to ask a question.

Construct a uicontrol that is either a popup or list box. Set the String value to a cell array of strings, each entry of which contains one line to be displayed in the uicontrol. In the callback for the control, get() the String property of the control and store that for a moment, and get() the Value property of the control and use that to {} index the string property. The result will be the file name you want to load. Use the functional form of load() to load it, such as

indata = load(Filename);

and then the fields of indata will be the variables saved in the .mat file.

The hardest part is next: getting the value you loaded out of the callback and in to a place you can use it. For that, see this FAQ
