Programming style [message #11744]

I have a general style/algorithm question.

I want to plot in a 3-D array an ellipsoid within an in ellipsoid where the
voxels between the boundaries are non-zero and else where zero.

The general function is (x/a)^2 + (y/b)^2 + (z/c)^2 = 1.0

I have already done this using for loops and conditional statements but it
occurred to me that there may be some IDL matrix-boolean logic combination
that could accomplish this in a faster and more 'elegant' fashion.

I am now open for suggestions?

Thanks in advance.
