Matlab: Symbolics: solve, subs, and symfun

This video introduces continues the subject of symbolics in Matlab. In this video I introduce and show examples of substitution and solving, as well as the symfun function. Symbolics are not a part of Matlab's standard library, so this code may not work on your version of Matlab. In Octave this code can work, but you need to install and load the symbolic package. You can learn more about that here: https://octave.sourceforge.io/symboli... This video is part of a series comprising a complete introductory course in Matlab / Octave.
