JonesLib.mc provides array math too.
Did you check it, Rob?

I've used array math in diverse stacks, but
i suspect that these operations could be still
much faster. I hope that someone helps me to
optimize the array math in these stacks.

<http://www.geocities.com/capellan2000/graphics_transformations_01.zip>
Matrices for Scale, rotate, translate and skew 2d
vector polygon graphics.

<http://www.geocities.com/capellan2000/Rotater_Manipulator_v1a.zip>
Matrices for Scale, rotate and translate 3d
graphics, represented as vector polygons.

<http://www.geocities.com/capellan2000/Eps_Import_V04.zip>
Matrices to calculate the points of a bezier graphic.
This matrix calculation is SLOWEST than the other
two handlers that do the same function... :-((
This matrix could be optimized in some way 
to work, at least as fast, as the other two handlers.

Message received! :-)
