Write a MALTAB script file for plotting the below surfaces by coloring the surface with a coluor map , appropriately naming the axis and titling the plot. z = sin(x^2 + y^2)*(x + y)−2*x/y for (x,y) ∈ [−3,3]×[−3,3]

how to solve this question

What have you done so far? What specific problems are you having with your code?

syms x y

h=ezsurf(sin(x^2 + y^2)*(x + y)-2*x/y )

xlim([-3 3])

ylim([-3 3])

colormap jet

Ugh. The jet colormap should definitely be avoided. That is why MATLAB changed its default:

colormap without an input returns the current colormap.

ezsurf() automatically applies the current colormap (which is to say, when it generates the surf object, it does leaves the face coloring default and the default is to use a colormap)

Thank you for the valuable input @Sir Walter Roberson.
