+NAME
+iseval -- evaluate the fitted surface at x and y
+.ih
+SYNOPSIS
+y = iseval (sf, x, y)
+
+.nf
+pointer	sf		# surface descriptor
+real	x		# x value, 1 <= x <= ncols
+real	y		# y value, 1 <= y <= nlines
+.fi
+.ih
+ARGUMENTS
+.ls sf      
+Pointer to the surface descriptor structure.
+.le
+.ls x, y
+X and y values at which the surface is to be evaluated.
+.le
+.ih
+DESCRIPTION
+Evaluate the surface at the specified value of x and y. ISEVAL is a real
+valued function which returns the fitted value.
+.ih
+NOTES
+ISEVAL uses the coefficient array stored in the surface descriptor structure.
+Checking for out of bounds x and y values is the responsibility of the calling
+program.
