Member Function Documentation

◆ CholeskyDecompose()

const QMatrix & QMatrix::CholeskyDecompose ( )

Cholesky Decomposition.

Perform a Cholesky decomposition of a matrix, A, IN PLACE.

A=LL^T

Where L is a lower triangular, with positive real values along the diagonal.

The input matrix must be positive definite, otherwise the function will return an error.

The output matrix has the components of the matrix L in the lower triangle and the components of L^T in the upper triangle. The elements in the diagonal (the overlap) are the same for both L and L^T.

The entire algorithm can be done in place. Resulting matrix resides in the same memory location as it did before.

◆ CholeskySolveX()
