You can load the .mat file to your GUI function workspace using

load('YourFile.mat')

Once the vaiabled are loaded and calculation is completed, you can save a variable (say xyz) back to mat file using

save('YourFile.mat','xyz','-append')

You can use the EVALIN function to load a .MAT file into the base workspace from a function. For example, you can place the following code in the callback function of a push button in your GUI:

filename = uigetfile('*.mat');
command = sprintf('load(''%s'')', filename);
evalin('base', command);

The variables in your mat file are getting loaded into a structure. You have named this structure tempX. In order to access the data, you need to use the structure name and the variable name:

data = tempX.varName;
