whitenv

Whitenv vectors.

Calling Sequence

[newVectors, whiteningMatrix, dewhiteningMatrix] =   whitenv(vectors, E, D, verbose);

Parameters

vectors :

Data in row vectors.

E :

Eigenvector matrix from function 'pcamat'

D :

Diagonal eigenvalue matrix from function 'pcamat'

verbose :

Optional. Default is 'on'

Examples

[E, D] = pcamat(vectors);
[nv, wm, dwm] = whitenv(vectors, E, D);

Description

Whitens the data (row vectors) and reduces dimension. Returns the whitened vectors (row vectors), whitening and dewhitening matrices.
