I have a matrix and I need to subtract every element from each other in each row. So, for example, if I have a matrix A=[1 2 3; 4 8 9] the result should be for example this B=[1 2 1; 4 5 1] - the sequence is not important. But I need to know that the result in the matrix B corresponds to a particular elements' subtraction in matrix A. So if I have for example a subtraction of 2-1, which is A(1,2)-A(1,1) in matrix A and the result is 1 in matrix B I need to know that 1 corresponds to A(1,2)-A(1,1) and keep track of it.
I have tried to do it with cycles and also with a "bsxfun" function but unfortunately can't get the correct result.
g=[1 3 8; 4 6 2];
I'll be glad if anyone can help me. Thanks
