New fast algorithms for matrix operations
WebWe provide a novel approach to the design of fast algorithms for matrix multiplication. The operation of matrix multiplication is reformulated as a convolution, which is implemented using pseudo-number-theoretic transforms. Writing the convolution as multiplication of polynomials evaluated off the unit circle reduces the number of multiplications without … http://www-scf.usc.edu/~hoyeeche/papers/matrix-rank_conf.pdf
