PARAFACFit

Location: CuBatch\Model_PARAFAC\PARAFACFit.m

function Model_Parameters = PARAFACFit (X,F,varargin);

Description:
Fit_Fun fitting the PARAFAC model to the array X using an ALS algorithm (the NWay toolbox implementation).

Inputs:
X: double array of data
F: number of components to extract.
varargin: the additional inputs (beside X and F) for the parafac function ..\Nway\PARAFAC.m (i.e. Options, Constraints, etc).

Outputs:
Model_Parameters: structure with three fields

• xfactors: cell vector with the loading matrices
• nbfactors: F
• iterations: number of iterations for fitting (Model_Parameters.iteration(1)) and refining  (Model_Parameters.iteration(2))

Called by:
Model_PARAFAC\Calculate via ValidateModel and FitModel

Subroutines:
Internal: None
External: NWay\parafac
