SCALE
Scale a point distribution specified by ifirst,ilast,istride
according
to the scale factors iscale,jscale,
and kscale.
One can substitute the syntax
pset get pset_name
for the ifirst, ilast, istride
variable to access a pset. The letters i,j,
and k in the scale
factors correspond to coordinates specified by one of the
geometry
types
[xyz (Cartesian), rtz (cylindrical),
rtp (spherical)].
For example,
if geometry = rtz
then iscale = radial
coordinate, jscale = theta
coordiante, and
kscale = z coordinate.
If geometry = rtp the iscale = radial coordiante,
jscale = theta coordinate and kscale = phi coordinate.
If the scaling
option is relative then the scaling factors are unitless multipliers
with reference to some geometric center (xcen,ycen,zcen).
If the scaling option
is absolute then the scaling factors are constants added on to the
existing coordinates. That is, absolute is really a translation rather
than a rescale.
