use Matlab code

(20pts) Given a function f(x,y) = y sin(xy)-x cos(y) + 2 for-rs x and-rs y S . a) Use MATLAB to generate the surface of the function over its domain with spatial increment of 0.01 in both the x- and y-directions. b) Use the MATLAB function max to find its absolute maximum over its domain. c) Add the maximum point to the graph in part a) and show its value in the legend. d) Use the MATLAB function min to find its absolute minimum over its domain and show its value in the legend Add the minimum point to the graph in part c) and show its value in the legend. e)
