Sgrayplot - smooth 2D plot of a surface using colors

Calling Sequence

Sgrayplot(x,y,z,[strf,rect,nax])

Description

Sgrayplot is the same as grayplot but the plot is smoothed. The function fec is used for smoothing. The surface is plotted assuming that it is linear on a set of triangles built from the grid:

______ | /| /| |/_|/_| | /| /| |/_|/_|

Enter the command Sgrayplot() to see a demo.

Examples 


x=-10:10; y=-10:10;m =rand(21,21);
Sgrayplot(x,y,m,"111",[-20,-20,20,20])
t=-%pi:0.1:%pi; m=sin(t)'*cos(t);
clf()
Sgrayplot(t,t,m)
