Abstract Value Members

  1. abstract def factor(): Factorization

    Factor a matrix into the product of two matrices without returning the two factored matrices.

    Factor a matrix into the product of two matrices without returning the two factored matrices. Allows for example skipping the computation of the Q matrix in QR factorization when it is not needed, e.g., for regression. Class implementing the 'factor' method should set 'factored = true'.

  2. abstract def factors: (MatriD, MatriD)

    Return the two factored matrices.

  3. abstract def solve(b: VectoD): VectoD

    Solve a system of equations, e,g., 'a * x = b' for 'x', using the factored matrices, by first performing forward substitution and then backward substitution.

    Solve a system of equations, e,g., 'a * x = b' for 'x', using the factored matrices, by first performing forward substitution and then backward substitution. Must factor before calling 'solve'.

    b

    the constant vector
