Many students ask me how do I do this or that in MATLAB. So I thought why not have a small series of my next few blogs do that. In this blog, I show you how to solve a nonlinear equation.
The MATLAB program link is here.
The HTML version of the MATLAB program is here.
%% HOW DO I DO THAT IN MATLAB SERIES?
