1. What is tkmatrix?
tkmatrix is an education mathematical program to manipulate matrices.
Matrices are part of linear algebra. It was developed for students to learn 
algoritms and test own calculation. Therefore tkmatrix can give
not even a solution but all algorithm steps as a protocol. It can calculate
with floatnumbers (and multiple precision float) and fractions. 
Solutions and protocols can be exported to ascii, html and latex files.
(other files are possible). The math-part of tkmatrix is
programmed in C++ as tcl-library and graphical interface in Tk/Tcl. 
The distribution includes the program matrix too. 
It is pure shellprogram tkmatrix without GUI.

2. Compile and Install
-compile configuration
old linux STL Library use string::erase not string::remove. 
If your Library (RedHat<5.1) know string::remove you must edit
makefile and uncommnet one line

-to compile change in tkmatrix-0.6 directory and do
   make

-Installation

it copy all necessary files in /usr/lib/tkmatrix and make 2
symbolic links
in /usr/bin. Documentation in dir docu will be not copied.
