tQRdst: Tensor QR Decomposition Using the Discrete Sine Transform

Description

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

Usage

tQRdst(tnsr)

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 \(k\))

Arguments

tnsr

: a 3-mode tensor
