... this is not a normal spreadsheet functionality.

Right, I gathered that, and wondered if anyone had programmed it in as a set of macros, etc, which is why I asked if anyone had done it vs if it was available as a native Calc function.

I think you need to explain a bit about what you need and give us some idea of your math sophistication.

Spotty, but not rudimentary.

diff and integral calc a little bit of diff EQ, some matrix algebra - mostly self-taught for the purposes of comp graphics.

pharmacokinetics, chemical equilibria and kinetics, thermodynamics, - lots of chemistry

I've worked a bit with Bernstein polynomials, Bezier splines/patches, FFT, autocorrelation, orbital dynamics, all sorts of things ...

If you just need a program that will give you a singular value decomposition you are probably better off with Python ...

I know that there is numpy, etc. Long term goal is to implement an SVD algorithm in a "proprietary" computer graphics application language. But I already have a few tools that DO the SVD.

What I need is to grasp how the matrices in the result manipulate/relate to the original data set.

The internals of the SVD are, at the moment, secondary to that, much like learning to change oil/tires on a car is "secondary " to learning to drive.

So right now, I'm just trying to find someone who has the ability to understand what SVD is, and is capable and willing to explain the application of the resulting matrices.

Thanks very much!
