Hello,

I have a mxn matrix of binary data. I want to write a code where I move multiple rows to specified position or index.

%For example consider my matrix
%    a b c d e f g h i j k l
H = [0 0 1 1 0 1 0 1 0 1 1 0;  %1
     0 0 0 1 0 1 1 0 1 0 1 0;  %2
     0 1 1 0 0 1 1 1 0 0 0 1;  %3
     0 1 1 0 1 0 1 0 1 0 0 1;  %4
     0 0 0 1 1 0 0 1 1 0 0 0;  %5
     0 1 0 0 1 0 0 0 0 0 1 0]; %6
%I want to move rows 3&4 to between 5&6.
%I want my resultant matrix to be -
%    a b c d e f g h i j k l
H = [0 0 1 1 0 1 0 1 0 1 1 0;  %1
     0 0 0 1 0 1 1 0 1 0 1 0;  %2
     0 0 0 1 1 0 0 1 1 0 0 0;  %5
     0 1 1 0 0 1 1 1 0 0 0 1;  %3
     0 1 1 0 1 0 1 0 1 0 0 1;  %4
     0 1 0 0 1 0 0 0 0 0 1 0]; %6
% I want  generalised code to keep changing select rows in a loop.
