I tried to write a code in matlab. The code is supposed to be an easy task. I just want to compute the gaussian density for a single value. This is the code:
iteration = 1;
for iter = 1:iteration
i = 1;
while(i 0.5
j = 1;
prob = 0;
disp("more than half");
prob = computeProb(X((i),1),theta.tau(j),theta.mu(j),sqrt(theta.Sigma(j)));
fprintf('prob: %f \n', prob);
else
j = 2;
prob = 0;
disp("less than half");
prob = computeProb((X((i),1),theta.tau(j),theta.mu(j),sqrt(theta.Sigma(j)));
fprintf('prob: %f \n', prob);
end
i = i+1;
end
end
And this is the function to compute the density:
function q = computeProb( x,pi,mu,sd )
q= 1/(sd*sqrt(2*pi)) .* exp(-((x-mu)^2 / (2*(sd)^2)));
End
The Problem is ,the result of prob does not work if the u1
