Details:

help zoom gives:

Given a numeric argument greater than zero, zoom by the given
factor.  If the zoom factor is greater than one, zoom in on the
plot.  If the factor is less than one, zoom out.  If the zoom
factor is a two- or three-element vector, then the elements
specify the zoom factors for the x, y, and z axes respectively.


Trying to set zoom factor for x & y, then x,y & z-axes:

>> zoom ([2 2])   # OK
>> zoom ([2 2 2])
error: zoom: invalid factor
error: called from
    zoom at line 107 column 11
>>


The switch statement in zoom.m starting on L.101 clearly has no provisions for
zoom factors in 3D, unlike the texinfo docs state.

(I hit this when investigating bug #44323 to check if I had overlooked the
obvious)
