MATRIX04.ZIP contains
READ .ME - this file
DEMO .C - demo how to use this package
DEMO .DAT - demo data
DEMO .EXE - demo executable for DOS
MAKEFILE.DOS - makefile for Turbo C 2.0
MAKEFILE.UX - makefile for Unix
MATRIX .DOC - matrix toolbox interface document
MATRIX .H - matrix header file (must include it)
MATADD .C - matrix addition
MATCREAT.C - matrix creation
MATDET .C - find minor, cofactor, determinant
MATDUMP .C - matrix dump
MATERR .C - matrix error handling routine
MATINV .C - matrix inversion
MATMUL .C - matrix multiplication
MATSOLVE.C - linear equations solver
MATSUB .C - matrix substraction
MATSUBX .C - submatrix operation
MATTOEPZ.C - create symmetric Toeplitz matrix
MATDURBN.C - Symmetrix Toeplitz matrix fast solving algorithm
MATTRAN .C - matrix transpose
-------------------------------------------------------------------------------
WHATS NEW in v0.1:
- +, -, *, inverse matrix operations
WHATS NEW in v0.2:
- Linear equation solver
- C-programmer-friendly C sources
WHATS NEW in v0.3:
- better data structure (more Object-Oriented)
- finding minors, cofactors, determinants
- Levinson-Durbin algorithm for symmetric Toeplitz matrix
WHATS NEW in v0.4:
- Revised method for minors, cofactors and determinants
whose time complexity is T(n^3) instead of nearly T(n!).
This is important when you want to find the determinant
of a matrix whose size is over 10 x 10.
- submatrix operator
- matrix formmated dump function
- brief matrix toolbox interface document included
HOW TO COMPILE:
1. DOS under PC - use Borland's Turbo C 2.0 make -fmakefile.dos
2 All Unix environment - make -f makefile.ux
