Gaussian distribution in Matlab

Hi All, I am trying to plot a amplitude Gaussian distribution in Matlab.

How to get a Gaussian normal plot for 3 differents moments of time? I have values only for M, A and D

[Durganshu]

What is A? Do you know anything about the variation of x as well?

Sorry, there's no A. I don't know anything about x ... I only know the values of M and D.

Try something like

>> M = 1; D = 1;  % Set your own values
c = @(t,x) M/sqrt(4*pi*D*t)*exp(-x.^2/(4*D*t));

x = -5:0.1:5;
t = [0.1 0.5 1];
C1 = c(t(1),x);
C2 = c(t(2),x);
C3 = c(t(3),x);
plot(x,C1,x,C2,x,C3),grid
legend(['t = ',num2str(t(1))],['t = ',num2str(t(2))],['t = ',num2str(t(3))]);

Thanks a lot!
