how can i convert this code into matlab R2015b?

[Sriram Tadavarty]

May i know what do you indicate the conversion of this code to R2015b? Just use the code in that MATLAB, provided all the functions are available in that version. Then, it should work.

[risky amalia]

For example fminunc in that code, there's fminunc too in matlab R2015b buat it doesn't work. Or i have made mistake? And then rosenbrock function. I don't know what it calls in matlab R2015b

What does "it doesn't work" mean, precisely? Show us...

Your code above includes the definition of rosenbrock_func. You must place that code in its m-file of that name in a location on your matlabpath; functions are not defined in the command wlndow inline.
