Syntax

SG=SGof2Dfunc([ff,ax,res,D])

Input Parameter

`ff`:		handle to the function; default is @sin
`ax`:		axis [xmin xmax ymin ymax]; default is [-10 10 -10 10]
`res`:		step size; default is max(dy,dy)/99;
`D`:		Socket height; default is '' ==> only surface

Output Parameter

SG: Solid Geometry

Examples


SGof2Dfunc(@cos,[-pi 2*pi -pi 3*pi],.1); SG=ans;     % creates just the surface without thickness
SGofSurface(SG.VL,SG.FL,0.5)                         % creates a solid from the surface  

SGof2Dfunc(@cos,[-pi 2*pi -pi 3*pi],.1,0)   % creates a solid with no socket
SGof2Dfunc(@cos,[-pi 2*pi -pi 3*pi],.1,1)   % creates a solid plus socket

zzz=@(x,y) x+y
SGof2Dfunc(zzz,[-pi 2*pi -pi 3*pi],.1,1)   % creates a solid plus socket
SGof2Dfunc(str2func('@(x,y)x*x-y*y'),[-1 1 -1 1],.1,1) ;SS=ans;  % creates a solid plus socket
view(0,90); viewsmooth(-30,30,200)

SGof2Dfunc(str2func('@(x,y)x*x-y*y'),[-1 1 -1 1],.01) ;SS=ans; 
SGofSurface(SS,'',.3)
