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.
