1.5 Contour graph - vtk_contour3



Function file: f = vtk_contour3 (x,y,z,c [fmt| prop, val])


Displays a contour plot defined by x,y,z matrices, where x and y are typically formed by meshgrid. c is an optional matrix to give a color scale.

Optional parameter fmt:
number of conts - parameter NConts


Examples:
[x,y]=meshgrid(-2:.2:2,-2:.2:3);
z=x.*exp(-x.^2-y.^2);
vtk_contour(x,y,z,'NConts',15)
