Dear expert.
I am just a beginner when it comes to using MATLAB. Would anybody be so kind and show me the rope of this particular problem? I would like to use this as the base for my further practice.
Let z = f(x, y) = 2x y − y 2 − 4x 2 + 3y.
Draw the contour plot of the function. Point out the local extreme and the saddle point on that figure.
I would like to express my gratitude to your concern!
