Hgtransform and makehgtform at fsurf

Hello,

I have a cone ecuation:

conefun = @(x,y,z0,phi) z0 + sqrt((x-x0).^2 + (y-y0).^2)*cotd(phi/2);
fsurf(@(x,y) conefun(x,y,10,90))

If the cone has the orientation you want, but not the location , you can add a translation to put it where you want,

set(t,'Matrix', makehgtform('translate',[tx ty tz],'xrotate',pi)
