- The '''Hama''' project utilises Groovy for simplification of computational language.
+ The '''Hama''' project utilises Groovy for simplification of computational language with
generalized the matrix Java Interface.
  For example, we can perform a parallel matrix multiplication by expressing as follows:
  {{{
+ Java API :
+   
+   Matrix a = Matrix.random(conf, 4, 4);
+   Matrix b = Matrix.random(conf, 4, 4);
+   Matrix c = a.multiply(b);
+   
+ Groovy :
+ 
    def a = rand(10,10)
    def b = rand(10,10)
    def c = a * b
