MATLAB: Generate row or column permutation

indexpermutationrowvectors

Hi, I have row and column vectors x,y respectivily
assume N=3 , x={0.587 0.344 .712} , y={ 0.987 0.952 0.689 } after that the ascending order of x&y as shown Bx=sort(x); By=sort(y); the result for that
Bx={0.344 0.587 0.712}, By={0.689 0.952 0.987}
My question here >>>How taking the index of Bx&By from x&y to generate row and column permutation vectors to obtain the result as mm={2 1 3},and nn={3 2 1 }

Best Answer

  • [c1,mn]=ismember(x,Bx);
    [c2,nn]=ismember(y,By);
