Set the shading of surface or patch graphic objects. Valid arguments for type are
"flat"- Single colored patches with invisible edges.
"faceted"- Single colored patches with visible edges.
"interp"- Color between patch vertices are interpolated and the patch edges are invisible.
If ax is given the shading is applied to axis ax instead of the current axis.
The following code
figure(1); clf
sombrero
shading faceted
title('shading "faceted"')
figure(2); clf
sombrero
shading interp
title('shading "interp"')
figure (3); clf
pcolor (peaks ())
shading faceted
title('shading "faceted"')
figure (4); clf
pcolor (peaks ())
shading interp
title('shading "interp"')
