title: Get parameter values from .m-file into GUI
body: <p>To keep it short, I'm developing a software tool where I would like to import
  parameters into GUI from .m-files, but I can't find how to import the parameters.
  I'm using <code>iugetfile</code> to 'reach it' but how do I insert the parameter values?</p>
  
  <p>If I open the file in MATLAB (command window), then I get the parameters in
  the workspace. Is there an easy way to read the parameters into GUI to be able
  to use them in functions there?</p>
