Re: gui in matlab

Take a look at this tutorial for getting started with GUI programming
under matlab:
http://dsp.ucsd.edu/students/present-students/mik/matlabgui/

You'd have to set up an m x n grid of inputboxes and then read those
into a matrix. matlab also has functions for loading bitmaps which
might be what you are looking for since you mentioned a "drawing".
