PasCmplx Complex Mathematics Unit for Borland Pascal.

PasCmplx was a response to the practical need for a quick and convenient unit
for complex mathematics. Unit PasCmplx includes all regular routines for
dealing with complex numbers as well as some service functions. Unit can be
used for Borland Pascal 7.0 DOS, DPMX and Windows programs.

All routines of Unit are written and optimized in assembly language using
coprocessor's commands.

They automatically determine the presence of 80387 (or higher) and use its
fast instructions.

Complex arguments are passed directly on stack (not through pointers) and
complex results are returned in 80x87 stack -- this makes all calls very
quick, much faster than calculation itself.

This package also includes unit PasFFT, which implements the fast Fourier
transform using PasCmplx routines.  See PASCMPLX.PAS for the instructions and
the list of functions, PASCMPLX.ASM for details of realization.

Files in the package:

PASCMPLX.PAS -- Pascal interface unit for PasCmplx with:
   -- the list of functions, variables and constants
   -- important instructions
PASCMPLX.ASM -- Assembler implementation of PasCmplx routines.
CMPLXTES.PAS -- Pascal program giving examples of using PasCmplx.
PASFFT.PAS   -- fast Fourier transform unit written using PasCmplx routines
FFTTEST.PAS  -- Pascal program with an example of using PASFFT.PAS
FFTTEST.FFT  -- sample data file for FFTTEST.PAS

No expressed or implied warranty, no responsibility for errors or omissions
(which you are very welcome to correct).
