Sommario
SiaA una matrice reale simmetrica di ordinen, B una matrice reale simmetrica di ordinen per cuix T B x>0 eC una matricen×p di rangor conr≤p<n. Si vogliono deteminare i vettorix per cui, JIMEL
è stazionaria eC T x=θ è il vettore nullo. È dato un algoritmo per generare un autosistema simmetrico i cui autovalori sono i valori stazionarì e per determinare i vettorix. Sono altresì presentate parecchie applicazioni dell'algoritmo.
