Greetings,
I thought this would be a smaller problem than it is turning out to be.
There is a bug in the MI 5.0 CentroidX, CentroidY and Centroid commands
that returns, not the region centroid, but rather a corner point. I've
noticed this both in region objects and in grids I've created (actuall

I've got the main part of my code working properly and would now like to

Thanks to help from this list, I was able to tackle the Alias variable and
use it in calling routines for multiple tables. Here's a bit of a twist.
I'd like to do the same thing with the Map and Create Table commands.. For

Recently I asked about higher math functions in MB and received the

A few days ago I asked about doing advanced mathematical operations in
MapBasic. I received one reply and some additional help from colleagues at
work. My needs were to do interpolation, sorting and matrix inversion,
among others.

I need to perform several math operations, the most difficult of which is
probably a large matrix inversion. Are there any add-on packages to help
do matrix operations?
