this is code correct

Hello I wanted to know if my code is correct for this type of equation

z = f(x, y) for  −2 ≤ x ≤ 2 and  −2𝜋 ≤ y ≤ 2𝜋
 where

f(x, y) = e−0.2x sin(2y)

THIS IS THE CODE I wrote

%Plot a function
f=@(x,y) (exp(-0.2.*x)).* sin(2.*y);
fimplicit(f,[-2 2 -2*pi 2*pi])

Answer 1

[Star Strider]

It appears to be correct, and the code runs without error.

Thank you so mcuh

[Star Strider]

My pleasure.

Chnage it to:

fsurf(f,[-2 2 -2*pi 2*pi])

.

Answer 2

[Walter Roberson]

The assignment to f appears to be correct, and the plotting bounds appear to be correct. However, nothing in the problem statement says that you are solving for f(x,y) = 0, so you should not be using fimplicit(). You should use fsurf() instead.

[Aminata camara]

thank you for the suggestion so then I just replace fimplicit by fsurf in the code?

[Walter Roberson]

yes

Answer 3

[Maria Quennie]

plot function 0 ≤ 𝑥 ≤ 2𝜋 using sin2(x)

I do not understand how this solves the original question? Please expand on how making this plot would help the original poster?
