Abstract
The optical matrix computing often plays a very important role in optical digital processing, many transformation and information processings in optics can be converted into a group of basic matrix multiplications1. Now, many approaches to implement such calculations have been provided2-4. But to all the existed schemes and systems, the difficulty is the long time sequence and the lower accuracy obtained, as well as a rather complicated system is required. In this paper, we have tried to use optical symbolic substitution method5 combined with the calculation of outer product of matrices to solve the multiplication of matrices. Preliminary experimental result has been obtained successively.
