Hey:)

So this is my problem:

I want to maximize the final mass of an ascending rocket into an orbit by controlling the trajectory over a thrust vector control variable a(t). So I need an Optimization Toolbox that returns me the optimal function a(t), but the objective function I want to minimize is m(t). And I couldn't find anything about this anywhere. I tried for example fmincon, but fmincon only returns a scalar.

Do you have any ideas?

Hi,

yes, there is functionalDerivative which is useful in this case. See the examples in the documentation. There is a tutorial for this function also, where you can learn how it works.

Best regards

functionalDerivative will return a symbolic result. Maybe it helps if you work through the Brachistochrone example, to understand what you can expect by using functionalDerivative.
