Mathomatic is a general-purpose computer
algebra system (CAS) that can symbolically solve, simplify, combine, and
compare algebraic equations, perform complex number and polynomial arithmetic,
etc. It does some calculus and handles all elementary algebra, except logarithms.
Plotting expressions with gnuplot(1)
is also supported.
rmath and matho
are shell scripts that allow you to use Mathomatic with input of functions
like sin(x) and sqrt(x) automatically expanded to equivalent algebraic
expressions by the m4 macro preprocessor. A matching pair of parentheses
is required around the parameters for all functions in m4 Mathomatic; m4
requires this. rmath also runs the rlwrap readline wrapper utility if available,
to provide readline input editing support similar to that provided by mathomatic(1)
.
The following general functions are defined when using rmath or matho:sqrt(x),cbrt(x),exp(x),pow(x,y),abs(x),sgn(x),gamma(x),floor(x),ceil(x),int(x), and round(x).
The following standard trigonometric functions
are defined: sin(x),cos(x),tan(x),cot(x),sec(x), and csc(x).
The following
hyperbolic trigonometric functions are defined: sinh(x),cosh(x),tanh(x),coth(x),sech(x), and csch(x).
The following named binary operators are
defined: mod for modulus.
The following universal constants are defined:
pi,e,i (the imaginary unit), euler,omega, and phi (the golden ratio).
Text files may be specified on the shell command line that will
be automatically read in through the m4 preprocessor into Mathomatic. After
any files are read in, Mathomatic prompts for input from the console.
Mathomatic
is best run from within a terminal emulator. It uses console line input
and output for the user interface. First you type in your mathematical equations
in standard algebraic 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.
Complete documentation
is available in HTML and PDF formats; see the local documentation directory
or online at "http://mathomatic.org/math/doc/
" for the latest Mathomatic
documentation.
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". For example, the line "no color" will make
Mathomatic default to non-color mode, which is useful if you aren’t using
a standard ANSI terminal emulator.
