WebApr 20, 2024 · I want to access fmincon's iteration number and function count within my function so I can name the input files to track the algorithm's progress. This is particularly important when I run fmincon in parallel as any nasty workarounds (global variables or writing files to disc) fail horribly and you end up with files with the same name. WebJan 25, 2024 · MPC That stands for model predictive control, which is a control technique that solves an optimization problem at every sample point for a defined future horizon (by this it determines the control law implicitly, so you don't need to do the nasty pole-placement in Laplacian-space). Anyway, you use fmincon to solve this optimization problem.

The theory behind Karush-Kuhn-Tucker's conditions for optimality in the cases of equality and inequality constraints is discussed. Description and foundation of nonlinear optimization

Webfmincon passes x to your objective function and any nonlinear constraint functions in the shape of the x0 argument. For example, if x0 is a 5-by-3 array, then fmincon passes x to fun as a 5-by-3 array. However, fmincon multiplies linear constraint matrices A or Aeq with x after converting x to the column vector x(:).
