Performance of modified Faddeev algorithm on optical processors

An optical processor realising the versatile Faddeev algorithm is programmable and can be used for several computations such as matrix multiplications, decompositions and inversions just by changing the structure of the data stored. Optical processors have round-off spatial errors and noise limiting the accuracy of computations. It is shown that the use of a preprocessed Faddeev algorithm on an optical processor can produce more accurate results than an optical processor realising the standard Faddeev algorithm. The procedure for preprocessing and possible optical realisations of the preprocessed Faddeev algorithm on optical processors are described. Simulation results show the improved accuracy of such preprocessed Fadeev algorithm based computations
