Program : mtx.exe
Author : Bill Forseth
1405 8th Ave N
Fargo, ND 58102
(701) 239-0150
Purpose - 1. Solves A|b matricies using Gauss-Jordan elimination.
2. Output adjustable, suitable for indirection
Syntax - mtx < input_data_file N [options]
where : input_data_file contains an N(N+1)
matrix in A|b form of integers or reals
N is the size of one column
[options]
-s (display the solution only)
-pn (n is the precision - defaults to 2)
When used in conjunction with 'randmtx' the following syntax
is suggested:
randmtx n | mtx n [opts] > out_file
Files : mtx.c,.h : main calling module and global defines
mtxcle.c,.h, : command line, error handling
mtxio.c,.h, : allocation, initialization,output display
mtxsolv.c,.h : G-J computations
randmtx.c : creates a random, variable n(n+1) matrix
(seperate executable program)
Compiler : Torbo C, v.2.0 (IDE)
Switches : small model,
8086 instruction set,
floating point emulation,
word alingment,
all debug info off,
register optimization
Updates - 1/4/91 - created
2/25/91 - optimized, modularized
5/29/91 - cleaned up, expanded
