Webb9 nov. 2024 · These results really supports the general answer, that Julia (at least on this specific task) is significantly faster in a case when Julia and Matlab code are realised simply by for-loop (1-thread ~ 2x). In a case when Matlab code is vectorized and run on 8 core CPU the Julia vectorized for-loop is still faster (~1.25x) .
