a=[1 0 0 0 1 0; 0 0 1 0 0 1;1 0 1 0 0 0;0 0 1 0 0 1;1 1 0 0 0 0;1 0 0 0 0 0;0 0 0 1 0 0];
I chose first row and wrote it as [ 1 1 0 0 0] and I want to rearrange the matrix depends on I, I used the index
a=[1 0 0 0 1 0; 0 0 1 0 0 1;1 0 1 0 0 0;0 0 1 0 0 1;1 1 0 0 0 0;1 0 0 0 0 0;0 0 0 1 0 0];
row=a(1,:);
s=find(row==1);
row1=[0 0 0 1 1 0];
s1=find(row1==1)
