      public static DMatrixSparseCSC mult(DMatrixSparseCSC A, DMatrixSparseCSC B, @Nullable @Nullable DMatrixSparseCSC outputC)
      Matrix multiplication C = A*B. Handles optional data structures requires by mult(DMatrixSparseCSC, DMatrixSparseCSC, DMatrixSparseCSC, GrowArray).
      Parameters:
      A - (Input) Sparse matrix. Not modified.
      B - (Input) Sparse matrix. Not modified.
      outputC - (Output) Storage for results. If null a new instance is returned.
      Returns:
      Results of matrix multiplication, the 'C' matrix
