    • RealExactSolver

      public RealExactSolver()
      Constructs an exact LU solver where the coefficient matrix is real dense.

  • Method Details

    • permuteRows

      protected Vector permuteRows(Vector b)
      Permute the rows of a vector using the row permutation matrix from the LU decomposition.
      Specified by:
      permuteRows in class ExactSolver<Matrix,Vector>
      Parameters:
      b - Vector to permute the rows of.
      Returns:
      A vector which is the result of applying the row permutation from the LU decomposition to the vector b.

    • permuteRows

      protected Matrix permuteRows(Matrix B)
      Permute the rows of a matrix using the row permutation matrix from the LU decomposition.
      Specified by:
      permuteRows in class ExactSolver<Matrix,Vector>
      Parameters:
      B - matrix to permute the rows of.
      Returns:
      A matrix which is the result of applying the row permutation from the LU decomposition to the matrix B.
