Thus,ezmeshc('u^2 - v^3',[0,1],[3,6]) plots u 2 - v 3 over 0 < u < 1, 3 < v < 6.ezmeshc(x,y,z) plots the parametric surface x = x(s,t), y = y(s,t), and z = z(s,t)over the square: -2π < s < 2π, -2π < t < 2π.ezmeshc(x,y,z,[smin,smax,tmin,tmax]) or ezmeshc(x,y,z,[min,max])plots the parametric surface using the specified domain.ezmeshc(...,n) plots f over the default domain using an n-by-n grid. Thedefault value for n is 60.ezmeshc(...,'circ') plots f over a disk centered on the domain.Remarksrotate3d is always on. To rotate the graph, click and drag with the mouse.2-142
