WebTo specify more than one output function or plot function, use the syntax. options = optimoptions ( 'solvername', 'OutputFcn' , {@outfun, @outfun2}); To use tab-completion to help select a built-in plot function name, use quotes rather than a function handle. Call the optimization function with options as an input argument. WebNov 7, 2024 · If I had to guess, the GPU cannot achieve faster speeds because fminunc requires that you pull the results of GPU computation back to the CPU after every call to the objective function. This is because fminunc has to do intermediate computations of its own which must take place on the CPU. birth emergency skills training pdf https://blazon-stones.com
