How can I do the same calculation multiple times for specified values of a variable

I am calculating compositonal profiles with a very simple version of the diffusion equation.
I want to do the same calculation several times and store the values in the workspace (ideally as mutliple columns for a single variable).
I have figured out the followng way to do it - but I am sure that there is a more elegant solution to my problem:
x = 0:1:100;
Co = 22;
t1 = 30000;
t2 = 60000;
t3 = 120000;
D = 0.001;
C1 = Co*erf(x/(D*t1).^0.5);
C2 = Co*erf(x/(D*t2).^0.5)
C3 = Co*erf(x/(D*t3).^0.5)
plot(x,C1, x, C2, x,C3)
Thanks
Cliff

Thios does the same as yoiur code, using a loop, and a simplified plot call:
x = 0:1:100;
Co = 22;
t1 = 30000;
t2 = 60000;
t3 = 120000;
t = [t1 t2 t3];
D = 0.001;
for k = 1:numel(t)
C(k,:) = Co*erf(x/(D*t(k)).^0.5);
end
figure
plot(x,C)
grid
It is may be a bit more efficient. I did not assess that specifically.

As always, my pleasure!
No worries. MATLAB has a lot of useful characteristics that take a while to learn about.
