I'd like for a pushbutton to open a .m file(when you run the .m file, a .fig file appears). How do I do that?
I actually don't know anything about MATLAB, this was just my officemate's work passed on to me.

you would first create a pushbutton in either GUIDE or manually using uicontrol. Then you would change the callback function to run a function that uses uigetfile() and the run() functions. see my example:
function test() %main function
%create the button and adjust the callback
btn = uicontrol('Style', 'pushbutton', 'String', 'Clear',...
'Position', [20 20 50 20],...
'Callback', @runfile);
%what the button does when clicked
function runfile(hobject,event)
[file folder]=uigetfile('*.m'); %prompt user to select mfile
run(fullfile(folder,file)); %fun the m-file.

Is it supposed to look like this?
% --- Executes on button press in pushbutton1.
function test()
btn = uicontrol('Style', 'pushbutton', 'String', 'Clear',...
'Position', [20 20 50 20],...
'Callback', @runfile);
function runfile(hobject,event)
[file folder]=uigetfile('performancegraph.m');
run(fullfile('C:\Users\USER\Documents\OJT-orig - Copy\home','performancegraph.m'));
% hObject handle to pushbutton1 (see GCBO)
% eventdata reserved - to be defined in a future version of MATLAB
% handles structure with handles and user data (see GUIDATA)
Oh, and thank you for answering my question ^___^

In that situation, you would use
function runfile(hobject, event)
run('C:\Users\USER\Documents\OJT-orig - Copy\home\performancegraph.m');

It does run but when I click the button, a clear button appears at the bottom left corner.
I clicked the clear button, and proceeded to open 'performancegraph.m', but this error appears in the command window.
Warning: Function C:\Users\USER\Documents\OJT-orig -
Copy\home\home.m has the same name as a MATLAB
builtin. We suggest you rename the function to avoid a
potential name conflict.

If you want the button in a different place or different size then change the parameter you are passing for Position.
The Warning is a warning and does not affect what comes after.
run() is able to find the directory you specified. However, there is no performancegraph.m there. Check for spelling mistakes, and check in case the actual file name has uppercase in some characters.
