New Package Released: PTAk

[Didier Leibovici]

PTAk_1.1-1 ( Principal Tensor Analysis on k modes) has been released on
CRAN
            A multiway method to decompose a tensor (array) of any
order,
             as a generalisation of SVD also supporting non-identity
metrics and penalisations.
             2-way SVD with these extensions is also available. The
package includes also some other multiway
             methods: PCAn (Tucker-n) and PARAFAC/CANDECOMP with these
extensions.

please send comments
+ looking for nice not too big multi-arrays for the next release demos
