The Cholesky decomposition of a real symmetric positive definite matrix A rewrites the matrix in the form A= LLT, where L is a lower-triangular matrix.
ComplexDenseCholeskyDecomposition can operate in two modes. In overwrite mode, the original matrix is overwritten with the result of the decomposition. In preserve mode, the original matrix is preserved, and a new matrix is created to hold the decomposition. You can set the mode through the Overwrite property.
ComplexDenseCholeskyDecomposition inherits from LinearOperator. This means you can use it to solve systems of linear equations where the matrix of the system is symmetric and positive definite. You can solve for a single right-hand side, or for multiple right-hand sides using the Solve(ComplexDenseVector, Boolean) method. You can also calculate the determinant the inverse, and an estimate for the condition number.
To solve a general (non-symmetric or non-positive definite)system of equations, use the ComplexLUDecomposition class instead.
