In rTensor2: MultiLinear Algebra

Tensor Eigenvalue Decomposition Using the Discrete Fourier Transform

Description

Performs a Eigenvalue decomposition of 3-mode tensor using the discrete Fourier transform.

Usage

tEIGfft(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)
