I have plotted f(x,y). I have obtained the maxima of the plot and now, I would like to know the values of x and y at which I have obtained this maxima.

doc max
shows you that there are two output arguments from the max function. The seconod gives you the location at which the max is found. The first, obviously, is the max itself. Those are your x and y. Or at least an index into an x vector, to be more precise.

maxval=max(f(:));
[xmax,ymax]=find(f==maxval);
