How do I compute the volume under an sfit surface (fo=fit([x​,y],z,'pol​y33') over the area of a polyshape (shape=polyshape(x,y))?

Hi,

Volume under sfit surface can be calculated using triplequad function.It evaluates the triple integral of function over the specified region

>> Triplequad(fo,xmin,xmax,ymin,ymax,zmin,zmax); 

Specify the arguments which are the coordinates of the ployshape
