% nuk is Innovation mean in Kalman Filter
% S is Innovation Covariance in Kalman Filter
% likelihood is the normal pdf
function likelihood = gauss_pdf(nukS)
% n = length(nuk); % calculating length
E = -1/2.*(nuk‘*inv(S)*nuk); %
% likelihood = exp(E)/((2*pi)^(n/2)*det(S)^(1/2));
likelihood = exp(E) / sqrt(2*pi*det(S));
