The function By the way, µ is the Greek letter, mu, not the Latin letter u, and ν is the Greek letter nu, not the Latin letter v.

It’s easy to confuse them.

is a Gaussian function.

a. Set µ = ν = 0 and σx = σy = 1, and plot G as a surface in three dimensions.

b. Change the values of µ and ν and plot G again. What do µ

and ν control?

c. Change the values of σx and σy and plot G again. What do σx and σy control?
