Matrix Plug-In for REALbasic 5 allows developers to construct programs
which, because of operator and function overloading, can handle real
matrices much like doubles and integers are handled. Matrix elements are
doubles. A matrix can be entered in standard form in a MultiLine EditField
and read in by a single instruction.

Included with the product are two REALbasic projects, one used for testing
while the other illustrates the ease of constructing a program which solves
a set of linear equations.

As a Carbon, PPC, and x86 plug-in, it can be used to build Mac OS X, Mac OS
9.x, or Windows applications.

Matrix Plug-In was programmed in C++ and compiled with CodeWarrior 8.3.
Freeware.
