Hello all, I need to compute a 3x3 matrix many many times, it is given by P = J x sigma x inv(F)‘, where J is a scalar, sigma and F are 3x3 matrices; A’ => transpose of A. What is the best way to compute this P as fast as possible in Julia?

Since the matrix size is very small, consider using SMatrix{3,3} from StaticArrays.jl
