- What is your algorithm for going down all rows of the matrix? Can row n of A only be swapped with row n of B based on comparing their distance or do you want to end with all the distances in B being shorter than all those in A or something else?
- As I understand it D is the distance from the 1st row of the matrix as a simple number of bits that are different. However, if you swap a row from B into A then wouldn't its distance then be measured against the top row of A rather than the top row of B which gives it its current distance?
how to swap rows between matrix?

hi guys,,, i have two matrix A & B, and i want to swap the rows between these matrix according to their Distance. the swap should be from B to A.it swap A rows with lower distance with B rows which have higher Distance. like row no.2 has D=14 and row 2 in B has D=16, so B_row should be swapped with A_row. how to do this? the matrix is below. help needed guys.

I'm not quite sure I fully understand the extent of the problem here. Can you give a full example of expected output?
e.g. I understand you want to swap row 2 of A with row 2 of B based on the distance in each, but that brings a few questions (and probably others):
I don't think I have time to consider a complete answer myself, but hopefully clarification on my questions will help someone else provide you with more of an answer.

Presuming you mean literally the simple-minded swap row-by-row depending on the D between the two, it's pretty simple.
Given A and B,
ixless=A(:,2)<B(:,2); % the offending rows
C=A; % need temporary copy
A(ixless,:)=B(ixless,:); % move needed elements of B into A
B(ixless,:)=C(ixless,:); % ditto to put A into B (C is still original A)
clear C

What you mean? The above uses whatever matrices A and B are; substitute variable names appropriately for your case.
