Wrapper for JAMA matrix operations for use in vectorJep and matrixJep. To add these functions to a VectorJep or MatrixJep instance use

    VectorJep j = new VectorJep();
    j.addStandardFunctions();
    ...
    JamaUtil.addStandardFunctions(j);

This will add a rank, inverse and solve function. `z = solve(x,y)` solves `x*z = y`. @see org.lsmp.djep.vectorJep @see org.lsmp.djep.matrixJep @see http://math.nist.gov/javanumerics/jama/
