PARAFACGNFit

Location: CuBatch\Model_PARAFAC\PARAFACGNFit.m

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

Description:
Fit_Fun fitting the PARAFAC model to the array X when compression or the dGN algorithm are required.

Inputs:
X: double array of data (currently limited to 3-ways)
F: number of components to extract.
varargin: the additional inputs (beside X and F) for the genparafac function.

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

Subroutines:
Internal: None
External: genparafac, paroptions
