tSVDdwt {rTensor2}

Tensor Singular Value Decomposition Using the Discrete Wavelet Transform

Description

Performs a tensor singular value decomposition on any 3-mode tensor using the discrete wavelet transform (Haar Wavelet).

Usage

tSVDdwt(tnsr)

Arguments

tnsr

: a 3-mode tensor

Value

a Tensor-class object

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

U: The left singular value tensor object (m x m x k)

V: The right singular value tensor object (n x n x k)

S: A diagonal tensor (m x n x k)
