List of the parameters for ps_plot() in Matlab after StaMPS

I have followed tutorials and there only one parameter is there, i.e., ‘u’. So can anyone tell me how to find more parameters, like finding wrapped phase, elevation,displacement, deformation etc.
It will be more helpful if I know what the parameter is for. For eg.,
ps_plot(‘u’)-> unwrapped phase

one topic is enough: Stamps export done. Matlab work done. How to view it again?
