How can I zoom in and out of 3-D plots within MATLAB?

The following example allows me to zoom in a 3-D plot:

mesh(peaks)

axis vis3d

zoom(2)

But there is no way to zoom out:

zoom(-2)

 ??? Error using ==> set

 Property value must be finite and greater than zero.

 Error in ==> e:\matlab5\nightly\toolbox\matlab\graph2d\zoom.m

 On line 217  ==>     set(ax,'CameraViewAngle',ncva);

I cannot find a way to zoom out of my 3-D plot.

The ZOOM function works on 3-D plots, but requires that you use the functional form of ZOOM to zoom in and out. In general, if you zoom in by a factor of X, you can zoom back out using 1/X.

For example:

zoom(.5)

to reverse the results, use:

zoom(2)

Negative numbers (for example, -2) are not valid zoom factors.
