conload.m

The function conload takes a dataset and a model (PCA, PLS, PARAFAC etc.) and calculates congruence

function Bcon=conload(X,model,mode,options);
%CONLOAD Congruence loadings for PARAFAC, TUCKER and NPLS
%  Determines congruence (earlier known as correlation) loadings 
%  for a specific mode of a model. Congruence loadings look at 
%  "non-average correlations", hence take differences in offset into 
%  account. 
%
%  Note that due to non-orthogonal loadings in PARAFAC, 
%  individual correlations can add to more than 1. Therefore, 
%  such loadings are not drawn with ellipses but squares 
%  added. Use options.force = 'ellipse' or 'square' to force 
%  one or the other on the plot. 
%
%  INPUTS:
%        X = nway data
%    model = parafac, tucker or npls model (plstoolbox structure)
%     mode = loading mode to investigate (i.e. mode = 1 for 
%                                             samples if they are in the 
%                                             first mode)
%
%  OPTIONAL INPUTS
%  options = modify options
%
%  OUTPUT:
%     Bcon = Congruence loadings
%
% I/O: Bcon = conload(X,model,mode);
