y = e^(-x^2)

I want to plot the above equation in matlab but i dont know how to plot please help or provide me code

Answer 1

[Azzi Abdelmalek]

x=0:0.1:10;
y=exp(-x.^2);
plot(x,y)

[Hamna Aziz]

(x^2)+3*(y^3)-25*z=100;

i am assigning this eqn a value. but matlab is giving me error every time. how to use this eqn in matlab?

[Rik]

Is this the exact code you're using? Because this isn't a valid Matlab syntax.

[Steven Lord]

Take a look at fimplicit3.

Answer 2

[Manka'a Abongnwi]

y = be ax sin(bx)(0.012x4 0.15x3 + 0.075x2 + 2.5x)

[Walter Roberson]

y = b.*exp(a.*x).*sin(a.*x).*(0.012*x.^4 + 0.075*x.^2 + 2.5*x);

Possibly

[Manka'a Abongnwi]

Wow after using the formula given by sir, everything worked well except the place to plot a graph of y and z versus x that's difficult

[Walter Roberson]

plot3()... except that you do not show any z variable.
