meditor sympy engine available

jscl-meditor is a java symbolic computing library with a text editor frontend. From version 3.0 onward, it is possible to substitute several script-based engines to the standard one (JSCL).

Today a new engine is available based on the renowned Python-based CAS SymPy, via Jython. Download it from:

jscl-meditor version 3.0 released

jscl-meditor is a java symbolic computing library with a text editor frontend. Version 3.0 introduces some major refactorings.

First of all, it is now possible to execute scripting code fragments, whereas previously evaluation of expressions only was possible.

Second, several script-based engines can be substituted to the standard one (JSCL). Two are currently available:

- JAS (the Java Algebra System) and its Jython front-end
- an experimental Scala engine, which for now just provides access to numerical scala.Math._ functions.... read more

jscl-meditor version 2.3 released

jscl-meditor is a java symbolic computing library with a text editor frontend. This new release provides a few major improvements.

First, an enhanced polynomial library, with a choice of various underlying data structures (array, list, tree), and improved coefficient types handling (factories). Coming along is a significant shrink of code redundancy, and many improvements in the Groebner basis engine. The latter has a new flags argument for enabling/disabling algorithm variations.... read more

jscl-meditor version 2.0 released

jscl-meditor is a java symbolic computing library with math editor. This release features the graphical rendering of math expressions (powered by Jeuclid), a complete rewrite of the interface and a partial rewrite of the engine, lots of improvements to the parser and the renderer, a "copy to wiki" operation, and a xhtml to LaTeX conversion utility.

jscl-meditor version 0.80 released

jscl-meditor is a java symbolic computing library with mathematical editor. In this release : an own Zaurus software package, brand new polynomial classes, improvement of the factorization code. The simplifier knows of additional trigonometric identities ; some new operations and functions (div, mod, matrix inverse, abs, sgn). The palm version is compiled in huge memory model (>64k).

jscl-meditor version 0.77 released

jscl-meditor is a java symbolic computing library with mathematical editor. What's new : the palm version was redeveloped from scratch. It has a simplified layout, can backup worksheets in the memopad ; the documentation is provided as a .pdb. The exceptions are now reported to the user. The former calculator-like look & feel is now closer to that of an editor. The engine is also improved, especially with the factorization which is now recursive, meaning that 1/(1+2*x+x^2) (factorize) yields 1/(1+x)^2. There are some changes in the syntax and the API too. Junit tests were developed to prevent regressions.
