.TH mtrxmath 1 "Sun Feb 18 2001" .SH NAME mtrxmath - Matrix Math .SH SYNOPSIS .B mtrxmath [\-asmdDih] .SH DESCRIPTION Allows for the quick and easy computation of various matrix functions and of matrices of different sizes. .SS OPTIONS .TP .I "\-a or \--add" Adds two matrices .TP .I "\-s or \--subtract" Subtracts two matrices .TP .I "\-m or \--multiply" Multiplies two matrices .TP .I "\-d or \--divide" Divides two matrices .TP .I "\-D or \--determinant" Finds the determinant of a matrix .TP .I "\-i or \--inverse" Returns the inverse of a matrix .TP .I "\-h, \-?, or \--help" Print usage and exit .SS USAGE Run mtrxmath followed by the function you want to execute. You can optionally specify files to load the matrices from in the order in which they would be used. If you only want to load from a file for the second matrix, try specifying `stdin` as the first file, but that hasn't been tested. .SS LOADING FROM A FILE Here is Paul Sack's Description of his File Input Code: The format is the same as that for the input (rows, whitespace, columns, whitespace, entries, each separated by whitespace). With the exception that any non-digits are ignored, so users can put comments in the files. e.g. rows: 2 columns: 2 1 2 3 4 is allowed. To utilize this new feature simply type 'mtrxmath [function] .SH BUGS People outside of the US have reported problems using the file loading features, however I have had no problems, and nobody in the US has reported problems. Also, I want to better format the output of the program. .SH HOMEPAGE The Matrix Math homepage is currently at http://foxxtrot.home.dhs.org/mtrxmath/ .SH AUTHORS Jeff Craig \- Maintainer .TP Paul Sack .TP Jake Wasserman .TP Cristoph Zurnieden .TP Florian Forster .TP Joel Stabis .TP Mark
