Truth I is the simulated powder diffraction pattern for BaTiO3 and Truth II is for ZnSe. The blue and red curves represent the true PDF and the extracted NMF components, respectively. a–d show the comparisons between components extracted with conventional NMF and (e–h) those extracted using the stretchedNMF algorithm.
