How can I plot the results for a for loop?

Hi,

I'm very new to matlab and I can't figure this out!

I need to write a for loop changing a single variable. I need to plot the results for each variable value. This is what I have so far

u=2.5
o=0.15
d=0:0.1:10
PSD=(1/(o*((2*pi)^0.5)))*exp(-((d-u).^2)/(2*o^2))
kc=0.865
for i=1:3
    dc(i)=i
    Td=1-exp(-kc*(d./dc(i)).^2)
    Solremoval=(sum(Td.*PSD)/sum(PSD))*100
    plot(Solremoval,dc)
end

Please help!

You should not use the variable names i and j as these are both names of the inbuilt imaginary unit. You might also like to place a semicolon after each line to prevent them printing to the command window.

Although figuring out non-functioning code is a little bit of a guessing game, this seems to prduce a similar result to what you are trying to do, via the very handy helper-function bsxfun and without any loops at all:

u = 2.5;
o = 0.15;
d = (0:0.1:10).';
PSD = (1/(o*((2*pi)^0.5)))*exp(-((d-u).^2)/(2*o^2));
kc = 0.865;
dc = 1:3;
Td = 1 - exp(-kc*bsxfun(@rdivide,d,dc).^2);
Solremoval = 100*sum(bsxfun(@times,Td,PSD))/sum(PSD);
plot(Solremoval,dc,'*-')

This produces the following figure:
