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.

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

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