Getting Started with Matlab – Part 1:

A lot of the math used for Machine Learning (ML) is linear algebra, actually a lot of engineering in general is based on the stuff. A matrix of numbers could represent everything from a circuit based control system, to a concrete pillar under a bridge. This also means that all the CAD software runs on the stuff as well. Its basically everywhere.

Linear algebra can be done by hand or you could do it using a programming language. You could be hardcore and write your own super optimized matrix inversion antilogarithms in C. Or even use python’s Numpy, or even R. However the industry standard is Matlab, these guys hold a virtual monopoly over the realm of engineering programming languages. When I say “engineering” I mean the hard physically based stuff like designing aircraft and rockets, or buildings.

Some would argue that Matlab is easier then Python, it is but only for linear algebra. You would not want to make your website in this stuff. Matlab works using a repal interface, all your variables are stored in memory and persist in your work space, this work space can be saved and loaded up again when you need it.

Below are some Matlab’s more basic commands.
