Using Matlab

5. a)Prompt user to enter values for xmin, xmax, ymin, ymax, and expression for fxy(x.y. b)Use usergiven expression to create inline function of two variables. c) Prompt user for the colormap specification and graph this function on the rectangle [xmin,xmax] by [ymin, ymax]. d) prompt user for coordinates of the point P(xl,yl) where xl,yl should be in the viewing rectangle xmin,xmax] by [ymin, ymax]. Use if end operator to check that usergiven xl,yl are in the rectangle, if not display error message and ask for new coordinates. e) plot point (xl.yl,fxl.yl)) on the surface with userdefined markersize and color
