WebOct 26, 2024 · Um, yes, you can use nested calls to fmincon, but with a huge, massive caveat. fmincon requires differentiability of the objective function. But the outut of fmincon will not in general be a differentiable function of the input! It can easily converge to different solutions depending on the staritng values, and the parameters in your function. north dallas pet grooming
