48 complex scalar multiplications. Which is at least 3 real multiplications.
- looofooo0 1y agoI think they completely misstated in the original paper what they did. It was a tensor decomposition of complex of 4x4 matrices up to the factor 0.5. Which is a nice result, but it is not really anything practical for a computer program doing 4x4 complex matrix multiplication.
