      public org.ejml.data.DMatrixSparseCSC apply(org.ejml.data.DMatrixSparseCSC A)
      Computes and applies the fill reduction permutation. Either A is returned (unmodified) or the permutated version of A.
      Parameters:
      A - Input matrix. unmodified.
      Returns:
      A permuted matrix. Might be A or a different matrix.
