Multivariate normal distribution density function implemented in javascript

How to use

var Gaussian = require('multivariate-gaussian');

var distribution_parameters = {
  // n*n covariance matrix
  sigma : [[1, 0.5], [0.5, 1]],
  // n-dimensional mean vector
  mu : [0, 0]
}

var my_gaussian = new Gaussian(distribution_parameters);

my_gaussian.density([0, 0]); // Returns the value of the density function at (0,0)
