MATHOMATIC(1)

NAME
mathomatic - automatic algebraic manipulator

SYNOPSIS
mathomatic [ -chqrtuv ] [ -m number ] [ input_files ]

DESCRIPTION
Mathomatic is a portable, general purpose CAS (Computer Algebra System) that can symbolically solve, simplify, combine, and compare algebraic equations, perform complex number and polynomial arithmetic, etc. It does some calculus and handles all algebra, except trigonometry and logarithms. Mathomatic is entirely hand-written in optimized C. It does not permit extremely large expressions, which can take a lot of memory and time. Instead reliability, ease of use, and speed are its features. All arithmetic is double precision floating point with 14 decimal digits accuracy.

OPTIONS

-c  Toggle color mode. This mode outputs ANSI escape sequences to make each level of parentheses a different color, for easier reading.

-h  Enable HTML mode (also valid XHTML) and disable readline input. This makes Mathomatic output suitable for inclusion in a web page. The color mode flag affects this mode, allowing HTML color output. It is recommended that the web page have a black background in color mode.

-m number
    Change the memory size of equation spaces. It is followed by a decimal floating point number which is a multiplier of the default equation size. Please don't set this higher than 10, unless you know what you are doing.

-q  Set quiet mode. Prompts are not displayed.

-r  Disable readline input processing.

-t  Set test mode. Used when testing and comparing output. Bypasses loading startup file, turns off color mode and readline, sets infinite screen width and height, etc.

-u  Guarantee standard output is unbuffered.

-v  Display version number and compile flags used and exit.

GENERAL
First you type in your algebraic equations in standard infix notation, then you can solve them by typing in the variable name at the prompt, or perform operations on them with simple English commands. Type "help" for the help command. If the command is longer than 4 letters, you only need to type in the first 4 letters. Most commands operate on the current equation by default. Documentation is available in HTML format, see the documentation directory or the web site "www.mathomatic.org".

ENVIRONMENT

EDITOR
    Editor to use for the edit command.

FILES

~/.mathomaticrc
    Optional startup file containing Mathomatic set options. It should be a text file with one set option per line. Do not include the word "set".
