You are an expert in writing code in many different languages. Your goal is to perform code completion for the following code, keeping in mind the rest of the code and the file meta data.
    Metadata details:
    filename: objfun.m
    path of file: ./repos/University_project_vmd_majorization/spo2
    
    the code of the file until where you have to start completion: function SeMin=objfun(para,x)
% para(1)-alpha 惩罚参数

    
function SeMin=objfun(para,x)
% para(1)-alpha 惩罚参数
% para(2)-K 分量个数
alpha=round(para(1));
K=round(para(2));

tau = 0;            % noise-tolerance (no strict fidelity enforcement)
DC = 0;             % no DC part imposed
init = 1;           % initialize omegas uniformly
tol = 1e-5;
%% VMD分解
[u, u_hat, omega] = VMD(x, alpha, tau, K, DC, init, tol);
%% 提取样本熵
[m,n]=size(u);
mm=2;
for ii=1:m
feature(ii)=SampEn(u(ii,:), mm, 0.2*std(u(ii,:)));%u的样本熵，0.2*std(imf1(1,:))表示求解样本熵r阀值，
