MATLAB Nonlinear Optimization with fmincon

This video tutorial covers solving a nonlinear optimization problem using MATLAB's fmincon function. It begins with an introduction to fmincon and available resources, followed by setting up the problem with constraints and bounds. The tutorial then demonstrates building MATLAB scripts for defining constraints and the objective function. It proceeds to solve the optimization problem using fmincon and concludes with analyzing the results, including checking constraint satisfaction and understanding outputs like Lagrange multipliers.
