Purpose
Calculates the Tucker3 core array given the data array and loadings
Synopsis
- Core = corecalc(X,loads,orth,Weights,OldCore);
Description
Caculates the core array given the data X and the loadings loads (component matrices) which are held in a cell (see TUCKER).
Optional input orth is set to 0 to tell CORECALC that the loadings are NOT orthogonal.
Optional input Weights allows a weighted least squares solution to be sought.
Optional input OldCore provides a prior estimate of the core to speed up calculations.
The output Core is the Tucker3 core.
