在 MATLAB Online 中打开

years       = transpose(2000:2008);
months      = transpose(1:12);
[row1,col1] = size(years);
[row2,col2] = size(months);
year_month = zeros(row1*row2,3);
for ii1 = 1:row1
    year_month((ii1-1)*row2+1:ii1*row2,:) = [repmat(years(ii1),[row2 1]) months repmat([1],[row2 1])];
end
datetime(year_month) % your answer
