 ezsurfc
 3-D surface and contour plotter Calling Sequence ezsurfc(f) ezsurfc(f,[min,max]) ezsurfc(f,[xmin,xmax,ymin,ymax]) ezsurfc(f,g,h) ezsurfc(f,g,h,[min,max]) ezsurfc(f,g,h,[xmin,xmax,ymin,ymax]) ezsurfc(...,gridsize) ezsurfc(...,'circ') Parameters

 f, g, h - algebraic expression min, max, xmin, xmax, ymin, ymax - (optional) numeric gridsize - (optional) integer 'circ' - (optional) Description

 • The ezsurfc function is the same as ezsurf except that a contour plot is drawn underneath the plot of f.
 • The ezsurfc(f) plots a three-dimensional surface.  When g and h are specified, a parametric surface plot will be generated.
 • xmin and xmax denote the left and right endpoints of the horizontal range.  ymin and ymax denote the vertical endpoints.  When xmax = ymax and xmin = ymin, the two number min, max form can be used.  When omitted, the default range is -Pi .. Pi.
 • When three expressions are given as the first arguments in the ezsurfc calling sequence, an implicitplot3d of f(s,t), g(s,t) and h(s,t) is generated.
 • When f, g or h are not functions of x, y, indets is used to find the indeterminates.  The range limits correspond to the order of alphabetically sorted indeterminates.
 • Specifying the gridsize option generates a plot over the grid region, gridsize x gridsize.
 • Specifying the 'circ' option causes the plot to be generated over a disk. Examples
