YAMP - Yet Another Matrix Program v1.5
Author: Mark Von Tress, Ph.D.
Date: 08/28/92

The programs contained in the archive are an upgrade of C++
matrix algebra package. The package supports recursive matrix
functions. Two memory models are available: in RAM and out of
RAM. In ram matrices are limited to 64k in size. External
Matrices are stored in a virtual memory file that can be stored
in a RAM disk, and is limited to 32 megs. Virtual matrices can
be larger than 640K. There is a tradeoff between speed and
memory requirements.

The in ram memory model works in all but the tiny memory model.
The virtual memory model compile under the large and huge memory
models of Turbo C++ v1.0, 2.0, 3.0, and 3.1. Microsoft C/C++
v7.0 compatability has been added. The documentation is written
in LaTex, so you will have to find an installation of LaTex
somewhere to print the document as a book. The text should be
readable in ASCII format if you ignore the TEX control
sequences. They begin with a backslash, '\'. Typical sequences
to ignore are \verb, \index, \cite,
\begin, \end. Also ignore the \ in \$.


Version 1.1
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

- 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

- 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

- SGREP has been removed, since the functions above have
been provided.

- The header virt.h has been docuemented 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.
Version 1.2:

This is an improved version of version 1.1

- A graphic object for X-Y plots. This requires Borland
graphics interface files.

- A 15 to 20 percent speed improvement using a deep-copy
trick on the stack. The stack now stores references
to the vectors in virtual matrices instead of copying
the matrix.

- An Index function for generating index matrices.

- Important, The virtual matrix copy constructor
performs garbage collection by calling cleanstack().
This means functions that use copy constructors
should also call Inclevel() before using
the copy constructor.

- Some bugs were fixed in the string operators '+'.
The names in Mexp, Mlog, Mabs, etc were fixed.
The make files work now for building a Borland
library. I also got sloppy and left out some
documentation files.

Version 1.3

- Added a statistical distribution function module.
It has the 4 main families of continuous distributions
used in applied statistics. The module also has
the inverses.

- Bug Fix: Scalar subtraction, M-a, was corrected. It
produced a-M since I just cut and pasted the M-a
routine above it. See Virtram.cpp or virtdsk.cpp
for the fix. You should also check for this in any
earlier versions of YAMP. It was in version 1.0 through
version 1.2.


Version 1.4

- Added division of a scalar by a matrix a/M.

- Fixed Index so it counts downward correctly

- Fixed a memory leak in the disk version copy
constructor. The hdr in the vdoub constructor
needed to be purged in the copy constructor, then
recreated by SetupVectors. This was not a problem
in the ram version.

- Added Microsoft V7.0 compatability to all but the
graphics module. A new graphics module is being
developed for MSC.

- Minor speed improvements using the define NO_CHECKING.
The range check in m(i,j), and Garbage() are skipped
at compile time if NO_CHECKING is defined. Garbage() is
still called, but the checks are not executed. Use
this option in finished code.

Distribution: I only plan to distribute this code over
networks. I also hope to tap other sources of distribution.
It is in the public domain, so it may be copied freely. I
have obtained a copyright as legal evidence of my
authorship. I do not plan to enforce it otherwise.

It cost me about $20US to mail this code on the continent.
(printing a manual, preparing the diskette, envelopes,
postage, and my time.). For those of you who do not have
access to LaTex, if you want a printed copy of the
documentation and a diskette containing the source code,
please send $20US to the address below. I will also keep a
record of people who contact me about the code.

My address for the next year or so is
