tensorBF (version 1.0.2)

undoSlabScaling: Postprocessing: Undo Slab Scaling

Description

undoSlabScaling reverts the slabs of the \(o^{th}\) mode to undo the scaling effect.

Usage

undoSlabScaling(Yn, pre)

Arguments

Yn

the normalized tensor data. This can be, for example, the output of reconstructTensorBF.

pre

The scaling values and mode used for preprocessing in the format as produced by normSlabScaling.

Value

The data tensor after reversing the scaling operation.
