Re: Performance of matrix arithmetic in Raku

Hi, raku doesn't have matrix operations built into the language, so you're probably refering to modules out of the ecosystem? Math::Matrix seems to have everything implemented in pure raku, which you should not expect to outperform pure python without some optimization work. Math::libgsl::
