mathomatic - automatic algebraic manipulator

-chqrtuv ] [ -m number ] [ input_files ]
Mathomatic is a general-purpose
CAS (Computer Algebra System) and calculator software that can symbolically
solve, simplify, combine, and compare equations, perform complex number
and polynomial arithmetic, etc. It does some calculus and handles all elementary
algebra, except 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 up to
14 decimal digits accuracy.
- -c
- Toggle color mode. This mode outputs
ANSI escape sequences to make each level of parentheses a different color,
for easier reading. Requires a terminal emulator that supports ANSI color
escape sequences. If the colors are too hard to see, try typing "set bold"
at the Mathomatic prompt to increase the brightness.
- -h
- Enable HTML output
mode (which is also valid XHTML). This makes Mathomatic output suitable
for inclusion in a web page. The color mode flag affects this mode, allowing
HTML color output. By default, Mathomatic uses maximum brightness colors
for HTML, so it is recommended that the web page have a dark background.
- -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
space size. Please don't set this higher than 10, unless you know what you
are doing.
- -q
- Set quiet mode. The startup message and prompts are not displayed.
This is useful when piping or redirecting input into Mathomatic, because
the input won't be displayed, so prompt output should be turned off.
- -r
- Completely
disable readline input processing. Readline allows using the cursor keys
and outputs terminal control codes which can be turned off with this option.
- -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, ignores pause command, etc.
- -u
- Guarantee standard output is
unbuffered.
- -v
- Display version number, compile flags used, maximum memory
usage, and then exit. The maximum memory usage displayed does not include
stack size (which varies) or executable size.
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" or "?" 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.
A command
preceded by "!" is taken to be a shell command and is passed unchanged
to the shell via system(3)
. "!" by itself invokes the default shell. "!"
is also the factorial operator.
Documentation is available in HTML format,
see the documentation directory or the official website: http://mathomatic.org
- EDITOR
- The EDITOR environment variable specifies which text
editor to use for the edit command.
- ~/.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".

The limit command is partially functional
and experimental and sometimes gives wrong answers. All else should work
perfectly, if not, report it via email to George Gesslein II <georgegesslein@gmail.com>.
Please include version information, which you can find by running mathomatic
-v or by entering the version command.
