WebMar 16, 2024 · FMINCON finds a constrained minimum of a function of several variables. FMINCON attempts to solve problems of the form: min F(X) subject to: A*X <= B, Aeq*X = Beq (linear constraints) X C(X) <= 0, Ceq(X) = 0 (nonlinear constraints) LB <= X <= UB (bounds) FMINCON implements four different algorithms: interior point, SQP, active set, … WebThe algorithm can use special techniques for large-scale problems. For details, see Interior-Point Algorithm in fmincon options. 'sqp' satisfies bounds at all iterations. The algorithm can recover from NaN or Inf results.
