## CONTOUR3 3D Contour Plot Function

Section: Handle-Based Graphics

### Usage

This command generates contour plots where the lines are plotted in 3D. The syntax for its use is identical to the `contour` function. Please see its help for details.

### Example

Here is a simple example of a 3D contour plot.

    --> [x,y] = meshgrid([-2:.25:2]);
    --> z=x.*exp(-x.^2-y.^2);
    --> contour3(x,y,z,30);
    Warning: Newly defined variable xlim shadows a function of the same name.  Use clear xlim to recover access to the function
    Warning: Newly defined variable ylim shadows a function of the same name.  Use clear ylim to recover access to the function
    Warning: Newly defined variable zlim shadows a function of the same name.  Use clear zlim to recover access to the function
    --> axis square;
    --> view(-15,25)
    Warning: Newly defined variable xlim shadows a function of the same name.  Use clear xlim to recover access to the function
    Warning: Newly defined variable ylim shadows a function of the same name.  Use clear ylim to recover access to the function
    Warning: Newly defined variable zlim shadows a function of the same name.  Use clear zlim to recover access to the function
