Dear Chief,
I generally try to make available to others units (with sources) that I have benefited from
Well, I'm glad to do that, but I have not written to the list advertizing my libraries because I figure that would be close to bragging about my code.
So, all are welcome to my utility library, which provides matrix inversion using GPC's dynamic schema types, simplex fitting, and a bunch of other stuff.

The only documentation is in the comments, so there's another problem: when I tell people they can use my code, I have to tell them how to use it also, or else my offer is rather empty.
Yours, Kevan
