tLUdct: Tensor LU Decomposition Using the Discrete Cosine Transform

Description

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

Usage

tLUdct(tnsr)

Value

a Tensor-class object

If LU decomposition is performed on a \(n x n x k\) tensor, the components in the returned value are:

L: The lower triangular tensor object (\(n x n x k\))

U: The upper triangular tensor object (\(n x n x k\))

Arguments

tnsr

: a 3-mode tensor
