Example 1. This example creates a dialog box for the image display function, prompting a user for an image name and a colormap name. The assignin function is used to export the user-entered values to the MATLAB workspace variables imfile and cmap.ssignin(ws, 'var', val) assigns the value val to the variable var in the workspace ws. The var input must be the array name only; it cannot contain array indices. If var does not exist in the specified workspace, assignin creates it.
