MATLAB Creating Graphical User Interfaces

• If you want to set the position or size of the component to an exact value, then modify
  its Position property.


• To add an image to a push button, assign the button's CData property as an m-by-n-
  by-3 array of RGB values that defines a truecolor image. You must do this
  programmatically in the opening function of the code file. For example, the array img
  defines a 16-by-64-by-3 truecolor image using random values between 0 and 1
  (generated by rand).

img = rand(16,64,3);

set(handles.pushbutton1,'CData',img);

where pushbutton1 is the push button's Tag property.

NoteSee ind2rgb for information on converting a matrix X and corresponding

colormap, i.e., an (X, MAP) image, to RGB (truecolor) format.
