I want to plot y = 2*exp((t.^2/)2) in MATLAB in the range of 0 to 3. I can't seem to get the vector length correctly and getting:
error using plot. Vectros must be the same length.
I understand that the vectors need to be the same length, but cannot actually implement this.
Code:
x = 0:0.1:3;
y = 2*(exp((t.^(2))/2));
plot (x,y,'r');
Without the 'x variable, the plot comes to:
plot (y,'r');
Comparing this to an online plotting tool for
gives:
Which does not seem to be exactly what I am getting as a result in MATLAB.
- Is the equation for plotting written correctly?
- How do I get the x-axis to range from 0 to 3?
Many thanks for any suggestions.

From the above expression, x is independent with y. And what about the x range. Clarify "A Spacing" means?

%Note: range t from - to +
t=-2:0.1:2;
%x=-3:0.1:3;
y=2.*(exp((t.^(2))/2));
plot(t,y,'linewidth',3);
