MATLAB: Without using loops

Question

 i have a large scale of data. i need to do the following job without using loops
  z=[1,2,3,4;5,18,7,8;12,16,35,-8];
  yuk=max(z(:,1:end));

i want to search "yuk" vectors elements in the "z" matrice. but i want to search yuk(1) only for first column of the z matrice , the yuk(2) to the second column of the matrice and so on. how can i do that

thanks

Answer 1

[yuk,idx] = max(z)
