Fix Sign Ambiguity of a Kruskal Tensor

Flips the signs of factor-matrix columns so that the largest-magnitude entry of each column is positive, compensating in the weights so the represented tensor is unchanged. Mirrors the MATLAB Tensor Toolbox fixsigns.

Usage

fixsigns(x, ...)

Arguments

x

A KTensor.

...

Additional arguments passed to methods.

Value

A sign-fixed KTensor.
