Fast matrix multiplication via recursive 4x4x4:48 algorithms into practice
Jean-Guillaume Dumas, Clément Pernet, Alexandre Sedoglavic +1
We present a fast algorithm for multiplying two 4x4 matrices using 48 multiplications and 216 other operations (addition, subtraction or scaling by a constant) over any ring contai…

A non-commutative algorithm for multiplying 4x4 matrices using 48 non-complex multiplications
Jean-Guillaume Dumas, Clément Pernet, Alexandre Sedoglavic
The quest for non-commutative matrix multiplication algorithms over non-commutative rings in small dimensions has recently seen significant progress. Specifically, the number of sc…
