Then A (X) and B (X) are fine but for C (X) it must be in the form c (X) < 0 so you'll need to break it into two constraints of that form. I pulled this example of how to specify a function for nonlcon from elsewhere in the documentation: WebThe flag tells the optimization function whether the optimization should stop ( true) or continue ( false ). The following examples show typical ways to use the stop flag. Stopping an Optimization Based on Data in optimValues The output function or plot function can stop an optimization at any iteration based on the current data in optimValues. siam unity industry co. ltd
