Question: 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.
