The GroovyLab environment aims to provide a MATLAB/Scilab like scientific computing platform that is supported by a scripting engine implemented in Groovy language. The GroovyLab user can work either with a MATLAB-like command console, or with a flexible editor based on the rsyntaxarea (http://fifesoft.com/rsyntaxtextarea/) component, that offers more convenient code development. GroovyLab supports extensive plotting facilities and can exploit effectively a lot of powerful Java scientific libraries, as JLAPACK , Apache Common Maths , EJML , MTJ , NUMAL translation to Java , Numerical Recipes Java translation , Colt etc. Also, GroovyLab supports Computer Algebra based on the symja (http://code.google.com/p/symja/) project.
Updated documentation for GroovyLab can be found at the wiki's of the jlabgroovy Google project (which is actually the same project), at page:
