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 and bold flags affect this mode,
allowing HTML color output.
- -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
- 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
that 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 an exclamation point ("!") is taken to
be a shell command and is passed unchanged to the shell (/bin/sh). "!" by
itself invokes the default shell, which is specified in the SHELL environment
variable. "!" is also the factorial operator.
Complete documentation is
available in HTML format; see the documentation directory or "http://mathomatic.org/math/doc/
".
- EDITOR
- The EDITOR environment variable specifies which text
editor to use for the edit command.
- ~/.mathomaticrc
- Optional startup
file containing Mathomatic set command 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. 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.
