-------------------------------------------------------------------------------
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

WHATS NEW in v0.41:
        -       bug fix for unix matrix creation

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
