Most notable among the new features are matrix decomposition algorithms, sparse matrices and vectors, genetic algorithms, new optimization algorithms, curve fitting algorithms, state derivatives in ODE step handlers, new multistep integrators, multiple regression, correlation, rank transformations and Mersenne twister pseudo random number generator.
