Library for evaluating algebraic expressions in Java

The JEL library enables users to enter algebraic expressions into their program. Since JEL converts expressions directly into Java bytecode, it significantly speeds up their evaluation time. If the user's Java virtual machine has a JIT compiler, expressions are transparently compiled into native machine code.

JEL may be a very useful tool for a variety of applications in science involving user-defined functions, e.g. to create plots, to apply fits to a data set and to solve integrals or differential equations. Another relevant use case for JEL is given by algebraic operations between two or more columns of a database table.
