tEIGdwt {rTensor2}

Tensor Eigenvalue Decomposition Using the Discrete Wavelet Transform

Description

Performs a Eigenvalue decomposition of 3-mode tensor using the discrete Wavelet transform (Haar Wavelet).

Usage

tEIGdwt(tnsr)

Arguments

tnsr

: a 3-mode tensor

Value

a Tensor-class object

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

P: A tensor of Eigenvectors (n x n x k)

D: An diagonal tensor of Eigenvalues (n x n x k)
