I'm depressed after knowing this. R/Python is only 12GB, while Stata is only about 23GB. Even SAS is about half of that.
Matlab installation file now over 23GB

What can matlab do that c/c++ with linalg / math kernel library cannot?
^^ I once solved arbitrary conics intersection (which can give rise to up to 4 intersection points) using Eigen library in C/C++ seamlessly as part of my larger project. Can I do this in matlab?

astronomers not astrologists. oh ffs this forum is a joke now.
You're comparing a fully bloated version of Matlab (with packages for engineers, astronauts and astrologists) with a striped down version of R. Stata, I won't even go there.
Do you honestly think astronomers use Matlab? We used IDL in the bad old days, but for a long time already we use almost exclusively Python (of course heavy simulations are done with some compiled language).
However, Matlab is wellsuited for astrology.

Which software do astrologists prefer?

The problem with Matlab is that its installation process is a mess, and sometimes useful functions are strewn across random toolboxes. So as an anticipatory measure you usually want to install a lot of toolboxes even if they’re not immediately necessary.
Compare to Python where you can install Anaconda once and get almost everything you might want, and then install a few more packages (perhaps even to their own environments so that you don’t contaminate the base environment) on an asneeded basis. Easier and also totally free.
