   * Flatten a multidimensional matrix into a single dimensional matrix.

   *

   *
   * Examples:
   *
   *    math.flatten([[1,2], [3,4]])   // returns [1, 2, 3, 4]

   * See also:
   *
   *    concat, resize, size, squeeze
   *
   * @param {Matrix | Array} x   Matrix to be flattened
   * @return {Matrix | Array} Returns the flattened matrix
