fun DoubleTensorAlgebra.cholesky(structureND: StructureND<Double>, epsilon: Double = 1.0E-6): DoubleTensor(source)
QR decomposition.
Computes the QR decomposition of a matrix or a batch of matrices, and returns a pair Q to R of tensors. Given a tensor input, return tensors Q to R satisfying input == Q dot R, with Q being an orthogonal matrix or batch of orthogonal matrices and R being an upper triangular matrix or batch of upper triangular matrices.
Receiver
the input.
Return
a pair of Q and R tensors.
Parameters
epsilon
the permissible error when comparing tensors for equality. The default is 1e-6 Used when checking the positive definiteness of the input matrix or matrices.
