    • inner_reorder_lower

      public static void inner_reorder_lower(org.ejml.data.DMatrix1Row a, org.ejml.data.DMatrix1Row b)
      Computes the inner product of A times A and stores the results in B. The inner product is symmetric and this function will only store the lower triangle. The value of the upper triangular matrix is undefined.

      B = AT*A

      Parameters:
      a - (Input) Matrix
      b - (Output) Storage for output.
