MATLAB: I do have a matrix A(n,n) and a matrix B(m,n) mB(k-1,j).

compare and classify elements of matrices with different dimensions

The question is to rank the element of each vector (column) in A(n,n) according to the order in B(m,n) and get a new matrix with these ranks. It is a classification of elements by column : example:
A = [0 4 7 ;
     1 3 5 ;
     3 3 6 ] 
B = [0 0 1 ; 
     3 1 2 ]
A(1,1)<=B(1,1)==>C(1,1)=1<—the index of zero in B;
A(2,1)>B(1,1)=0 && A(2,1)<=B(2,1) ==> C(2,1)=2
A(3,1)==B(2,1)> B(1,1)=0 ==> C(3,1)=2 and go next to the second column, then next one to get
   C=[1 2 2, C(:,2),C(:,3)]

Best Answer

You can create three nested loops for i, j and k. and check for your condition:
if ((A(i,j)<=B(k,j) && (A(i,j)>B(k-1,j))
Take care that, when k=1, you cant check both the conditions and only the first conditions is to be applied.
Hope it helps.
