I was a convert when I rewrote a code that I had originally developed in Matlab. The code I’d written was intended to improve a commercial software I use at work that was painfully slow and completely manual. Thanks to writing the algorithm myself in Matlab I was able to improve the performance significantly and was automated. I rewrote the code in Julia and due to a number of things I was able to cut my LOC by ~20x, reduce required memory by orders of magnitude, and get a sizeable speedup.
I posed the basics of the problem to the Julia discourse and received great feedback from the community.
Here’s a graphic I made for management shortly after my Julia rewrite. All told ~20,000 faster than the commercial code for a big-small (10k cells) problem and it made large problems (1M cells) tractable.
