Creating a gradient ascent matlab function?

I have to create a gradient ascent matlab function that finds the maximum of a function of two variables. It can call a function that uses the golden section method to find the maximum of one function, but I don't know how to use this to do it for two variables. Does anyone know how to do this?

It is the same as gradient descent except that you don't multiply your step by a negative sign. So your step has the same sign as your gradient (or hessian in higher dimensional problem).

check this.
