MATLAB中高斯混合模型的均值和中值计算

如何计算具有三个组件的高斯混合模型的平均值和中值，如MATLAB中的以下参数：

先验值[0.4,0.25,0.34]

中心[0.44；0.74；0.05]

协方差[0.03,0.18,0.03]

以下是计算高斯混合模型（GMM）平均值和中值的MATLAB代码：

N个GMM的平均值计算：

for i = 1:N
   mu = center{i};
   p = prior{i};
   mean_mix(i) = mu(1)*p(1) + mu(2)*p(2) + mu(3)*p(3);
end

median = zeros(N,1);
for i = 1:N
    for j = 2:N
         if (fix(trapz(x(1:j), gmm_pdfs(1:j,i))*100) == 50); 
             median(i) = x(j);
         end
    end
end

N gmm的中值计算：

for i = 1:N
   mu = center{i};
   p = prior{i};
   mean_mix(i) = mu(1)*p(1) + mu(2)*p(2) + mu(3)*p(3);
end

median = zeros(N,1);
for i = 1:N
    for j = 2:N
         if (fix(trapz(x(1:j), gmm_pdfs(1:j,i))*100) == 50); 
             median(i) = x(j);
         end
    end
end

注：gmm_PDF是针对x的评估PDF
