How do I change my scalars to fit my normpdf?

Here's my code (I am not using the normpdf function because the problem specifically asks to write out the whole equation to get the answer)

e = 2.7183;
xq = 0:100; 
mu = [25, 50];
sigma = [5, 10];
figure(3)
for ii2 = 1:length(xq)
    ndist=(1/(sigma*sqrt(2*pi)))*power(e,-(1/2)*(power(xq-mu)/sigma),2)
    subplot (2,1,ii2)
    bar(ndist)
end

Please explain what you are trying to do. I can't deduce it from your errorneous code.

I am trying to plot 2 normal distributions using the parameters above the for loop

Answer 1

[Torsten]

xq = 0:100; 
mu = [25, 50].';
sigma = [5, 10].';
ndist = 1./(sigma*sqrt(2*pi)).*exp(-((xq-mu)./sigma).^2);
plot(xq,ndist)
grid on

Thank you so much! This is much cleaner than what I typed for sure

Note that "mu" and "sigma" are column vectors and "xq" is a row vector.

Thus "pdist" will come out as a matrix:

xq = [1 2 3];
mu = [3 4].';
sigma = [2 9].';
(xq - mu)./sigma

ans = 2x3

-1.0000 -0.5000 0 -0.3333 -0.2222 -0.1111

This is already "advanced" MATLAB. Alternatively, you should try to produce "pdist" using a loop.
