Question

In my research, I have to identify row and column which has same value in matrix.

here for example the form of matrix:

A= [60    27    45    72    22    14    56     2     8    39    18    12;
    72    27    60    45    11     7     3    23    41    17    56    39]

Then, I want to identify row 1 until 4 in column 1 and column 2.

here part of my code.

    done =all(ismember(A(1,1:4),A(2,1:4))); %Code that I want to ask you.

Please Look at in row 1-4 and column 1-4;

if I use above code, done will always give true (1). but it is not my desire, because A(1,1) is not same with A(2,1), then A(1,3) is also not same with A(2,3), A(1,4) is also not same with A(2,4).

Answer 1

If you want to check whether the values in A(1,1:4) are the same as in A(2,1:4) you could just use

done =all(A(1,1:4) == A(2,1:4));
