Creating a simple plot

Im trying to plot y=x*e^(-x^2) where the range of x is from -3,3

Ive tried running

x = -3:3; y = x*exp(-x.^2); plot (x, y) however i keep getting the error Inner matrix dimensions must agree. Not quite sure what that means

Answer 1

[Rick Rosson]

Use .* instead of * here:

   y = x.*exp(-x.^2);

Also, you will want higher resolution:

   x = -3:0.01:3;

Answer 2

[Michael Haderlein]

You need element-wise multiplication:

x = -3:3; 
y = x.*exp(-x.^2); %<-- here, I added the point
plot (x, y)
