Symja - a symbolic math system written in Java based on the MathEclipse libraries

>>> Try it via Java Web Start! <<<

Features

• arbitrary precision integers, rationals and complex numbers
• polynomials
• differentiation
• pattern matching
• linear algebra

Usage

Examples in the console application:

org.matheclipse.core.eval.Console [options]

Program arguments: 
  -h or -help                  print this message
  -f or -file <filename>       use given file as input script
  -d or -default <filename>    use given textfile for system rules
To stop the program type: 
exit<RETURN>
To continue an input line type '\' at the end of the line.
