In this chapter we have explained how to multiply matrices using commutative algorithms that cannot be applied recursively. We started with the first result from 1968. Then we looked at later results up to 2023. Finally, we presented algorithms for the 3x3 problem in 22 and 21 multiplications.

摘要

In this chapter we have explained how to multiply matrices using commutative algorithms that cannot be applied recursively. We started with the first result from 1968. Then we looked at later results up to 2023. Finally, we presented algorithms for the 3x3 problem in 22 and 21 multiplications.
