Type Parameters

T

The QL decomposition of a matrix A rewrites the matrix in the form A= QL, where Q is an orthogonal matrix, and L is a lower-triangular matrix.

The QLDecomposition<T> class has no constructors. Instead, use the GetQLDecomposition() instance method to create an QL decomposition for a matrix.

QLDecomposition<T> can operate in two modes. In overwrite mode, the original matrix is overwritten by 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.

QLDecomposition<T> inherits from LinearOperator<T>. This means you can use it to solve systems of linear equations. You can solve for a single right-hand side, or for multiple right-hand sides using the Solve(Vector<T>) method. You can also calculate the determinant, the inverse, and an estimate for the EstimateConditionNumber().
