tQRdct {rTensor2}

Tensor QR Decomposition Using the Discrete Cosine Transform

Description

Performs a QR decomposition of 3-mode tensor using the discrete Cosine transform.

Usage

tQRdct(tnsr)

Arguments

tnsr

: a 3-mode tensor

Value

a Tensor-class object

If QR decomposition is performed on a n x n x k tensor, the components in the returned value are:

Q: An orthogonal tensor (n x n x k).

R: An upper triangular tensor (n x n x k)
