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

Use .* instead of * here:
y = x.*exp(-x.^2);
Also, you will want higher resolution:
x = -3:0.01:3;

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