3D Plotting

Question 1

How can we plot a surface using anonymous functions?

Answer 1

fsurf(anonymous_funct)

Question 2

How do we show contours or level curves with fsurf?

Answer 2

fsurf(f, “ShowContours”, “on”)

Question 3

How to create a surface using matrices?

Answer 3

We have two vectors x and y.
[X, Y] = meshgrid(x,y)

Z = F(X) + G(Y)

surf(Z)
