PARAFACScaErr

Location: CuBatch\Model_PARAFAC\PARAFACScaErr.m

function err = PARAFACScaErr (x,f,A,B,C,...,a,b,c,...);

Description:
Euclidean distance between two sets of loadings vectors (only for the f-th component) for a PARAFAC model.

Inputs:
x: vector with the scaling factors for the first M-1 modes (the last is given by the inverse of the products of the elements).
f: factor (i.e. column) to be "compared"

A
,B,C,...
: first set of loadings
a,b,c,...: second set of loadings

Outputs:
err: Euclidean distance

Called by:
Model_PARAFAC\FacOptScale

Subroutines:
Internal: None
External: None
