Expand description

The QR decomposition (with column pivoting) of a general matrix.

Implementations

Computes the ColPivQR decomposition using householder reflections.

Retrieves the upper trapezoidal submatrix R of this decomposition.

Retrieves the upper trapezoidal submatrix R of this decomposition.

This is usually faster than r but consumes self.

Computes the orthogonal matrix Q of this decomposition.

Retrieves the column permutation of this decomposition.

Unpacks this decomposition into its two matrix factors.

Multiplies the provided matrix by the transpose of the Q matrix of this decomposition.

Solves the linear system self * x = b, where x is the unknown to be determined.

Returns None if self is not invertible.

Solves the linear system self * x = b, where x is the unknown to be determined.

If the decomposed matrix is not invertible, this returns false and its input b is overwritten with garbage.

Computes the inverse of the decomposed matrix.

Returns None if the decomposed matrix is not invertible.

Indicates if the decomposed matrix is invertible.

Computes the determinant of the decomposed matrix.

Checks if self is actually part of its subset T (and can be converted to it).

Use with care! Same as self.to_subset but without any property checks. Always succeeds.
