ezmesh(f) generates a three-dimensional mesh plot.  When g and h are specified, a parametric mesh plot will be generated.

xmin and xmax denote the left and right endpoints of the horizontal range.  ymin and ymax denote the vertical endpoints.  A short-hand of min and max can be used when xmax = ymax and xmin = ymin.  When omitted, the default range is -Pi .. Pi.

When three expressions are given as the first arguments in the ezmesh 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.
