Hello guys...
Please I have this code
How can I subtract each row from all other rows(R) ... like subtracting R1-R1; R1-R2, R1-R3... R1-Rn+1 AND
then R2-R1, R2-R3.... R2-Rn+1 for all the rows
A1 = [...
0 0 1 1 1
0 1 1 1 1
1 1 1 1 1
1 1 1 1 1
1 1 1 1 1
0 0 1 1 1
1 0 1 0 1
0 0 0 0 1
1 1 1 1 1
1 1 1 1 1
0 1 1 1 1
1 0 1 0 1
0 0 1 0 1
1 1 1 1 1
1 1 1 1 1
1 0 1 1 1
0 0 1 1 1
0 1 1 1 1
1 1 1 1 1];
I need this urgently....
Thanks

Aa= reshape(a',1,size(a,2),[])- a; % a your matrix , each page of Aa represents each row’s subtraction
A=reshape(permute(Aa,[2,1,3]),size(a,2),[]).'

Wanted = bsxfun(@minus,reshape(D.',1,size(D,2),[]), D) % the reason was your using version prior to 2016b, that's why when you ask a question you should fill up the field "Release" thereby these kinds of misunderstandings can be avoided
