Graph-matrix calculus (GPH), Subdifferential plot
gph_plot(gph1, ..., gphN)
matrices. Functions in GPH matrix form, whose subdifferentials will be plotted.
Plots the subdifferential of each of the functions gph1, ..., gphN in turn, on the current graphics window. Plots the piecewise linear interpolation of the points stored in the ith matrix with colour i, and puts a mark at each of the points with style -i (via plot2d).
