Matlab is created with the intention of programming for numerical computing. While this would be a great language to learn first for people in engineering, science, and math who want a language to suit their careers, people with other or more diverse aspirations may best look elsewhere.

Nearly every programming language is free. Matlab licenses cost hundreds of dollars, so unless you work for a company or institution that can cover the upfront cost, you can't even use Matlab without paying a lot out of pocket.
