Provides a domain specific language (DSL) for math engineering (matlab-like syntax).
Module Overview
GroovyLab is a set of Groovy classes and Java libraries. It provides common linear algebra and plot static methods easily usable in any groovy script or class.
GroovyLab is fully usable, but still in development status. It is based on JMathTools Java API (based on JAMA and RngPack).

The following example shows GroovyLab in action:
import static org.math.array.Matrix.* import static org.math.plot.Plot.* def A = rand(10,3) println A plot("A",A,"SCATTER")
import static org.math.array.Matrix.* import static org.math.plot.Plot.* def A = rand(10,3) // random Matrix of 10 rows and 3 columns def B = fill(10,3,1.0) // one Matrix of 10 rows and 3 columns def C = A + B // support for matrix addition with "+" or "-" def D = A - 2.0 // support for number addition with "+" or "-" def E = A * B // support for matrix multiplication or division def F = rand(3,3) def G = F**(-1) // support for matrix power (with integers only) println A // display Matrix content plot("A",A,"SCATTER") // plot Matrix values as ScatterPlot def M = rand(5,5) + id(5) //Eigenvalues decomposition println "M=\n" + M println "V=\n" + V(M) println "D=\n" + D(M) println "M~\n" + (V(M) * D(M) * V(M)**(-1))
