16.07.2020 · Recently, I have been working on a project which requires translating Matlab code to R code. This project uses a fairly large dataset and needs to recursively compute the inversion of a matrix (around 1000 by 1000) more than 500 times. In Matlab, it spends less then 5 minutes to run the whole computation; while in R, my initial translation ran more than an hour.
