Version 1.1

Version 1.0 was released last March. I have used it throughout the year to write a little language and several other matrix programs. It has been very stable and run for several hundred hours on the machines I use. I thought about a few things during the year that seemed reasonable to add.

This upgrade of YAMP provides several new functions, and an improvement or two:

an in ram version that works for all but the tiny memory model.
User code for the in-ram and virtual memory model is identical.
Important: I removed the initialization to 0 of virtual matrices, so programs written in YAMP 1.0 must be adapted if they use the assumption that a matrix starts as a zero matrix. This increases the speed considerably.
A copy constructor that allows statements like "VMatrix V = Inv(Tran(X)*X);" to work as expected. Version 1.0 had a problem with this because it did not have a copy constructor.
Many new functions: determinant, cholesky decomposition, QR decomposition, singular valued decomposition, generalized inverse, a nearly fast fourier transform (and inverse), vec, vecdiag, diag, shape, sum, sum of squares, cumulative summation, max, min, and elemetary row and column operations.
A make file for constructing a library from YAMP.
SGREP has been removed, since the functions above have been provided.
The header virt.h has been documented so that it can be used as a quick reference.

About the only other thing I can think of needing in a matrix package is a graphics object. I'm still working on it and hope to finish it by this Spring or Summer. This is still one of my after hours hobby type projects, so I can't promise much.
