function [B,err,errglob,PxY,vexpvi,Avi,Bvi,vexpX,Ax,Bx] = regressvctuckervi (X,Y,rx,ryvi);
Description:
Executes a cross-validation (1 by 1) for IV-Tucker(rx,ryvi)

B: regression coefficient matrix
err: error of prediction by cross validation
PxY: the projected of Y on X.
vexpvi: Explained variation for Tucker(PxY)
Avi: score of Tucker(PxY).
Bvi: loadings of Tucker(PxY).
vexpX: Explained variation for Tucker(X)
Ax: score of Tucker(X).
Bx: loadings of Tucker(X).
