WebDec 12, 2012 · f = PV_design_code (x7,x8,x9,x10); The variable "f" represents the value of the objective function (i.e. the weight of the pressure vessel). To calculate the value of f, FMINCON is expected to call up the robust design alogrithm ("PV_design_code"), with the four variables determined by the FMINCON algorithm.

WebSep 8, 2013 · Accepted Answer: Matt J DiffMinChange and DiffMaxChange are options that can be specified, for example, when running fmincon. According the MathWorks website, they stipulate the "Minimum [Maximum] change in variables for finite-difference gradients (a positive scalar)." However, I am not finding that these variables work in a predictable way. WebDiffMinChange: positive scalar {1e-8} Minimum change in variables for finite difference derivatives.

WebDiffMinChange is an option for controlling finite difference steps the solver takes to estimate derivatives. It does not directly relate to the step size that the solver takes in its iterations. Usually it is safe to ignore this option, but if you are optimizing a simulation or ODE, consult Optimizaing a Simulation or ODE.
