title: Permutation matrix in matlab
body: <p>I have two vectors v1 and v2. Are there any matlab function that can find permutation T matrix between v1 and v2 so that T*v1 = v2 in matlab?  Actually, I know how to find permutation matrix by hand when vectors are short. I just don't know how to find that matrix using matlab function when vectors' size is very long.</p>
  
  <p>Thanks.</p>
