A lot of engineers want to use Matlab (code-based approaches, in general). Another whole lot gives up before had started coding because it’s hard.
In this case, having a good reference point is fundamental. At least to learn the very basics and start to explore all the possibilities of this programming language.
This is the online course that I wish I had when I started using Matlab. It is not free ($20), but it is worth it. It gives you a good bump to start learning this software in the correct way. You can check it out here.
