Class CholeskyDecomposition

The Cholesky decomposition of a matrix. Given a matrix A, the Cholesky Decomposition of A is L such that A = (L)(L.transpose). Only works for symmetric, positive definite matrix A.

Constructors

Properties

lowerTriangularMatrix: Matrix

A lower triangular matrix L such that A=(L)(L.transpose) This will ONLY be the case if A is positive-definite.

Methods

  • true if A is positive definite (and therefore we could perform the decomposition)

    Returns boolean

  • Given column vector b, solve for x such that Ax=b.

    Parameters

    Returns Matrix

    Throws

    if A is not positive-definite
