Set up the ten-by-ten matrix which has +1’s in the first super diagonal (directly above the leading diagonal) and −1’s in the sub-diagonal (directly below the leading diagonal). By this point you should be reasonably confident about how to set up a variety of matrices, either by directly typing in the elements or by exploiting structures within the matrix. We pause here to make sure that you are able to understand how to extract parts of matrices. Before proceeding make sure you understand what the commands a(:,1), a(2,:), a(2:3,:), a(:,:), a(1:2:3,2) and a(1,3:-1:1) give (you could try them for the matrix a = [11 12 13; 21 22 23; 31 32 33], where this has elements which reflect the labels of the elements). To help you understand these commands type 1:2:3 which gives the result [1 3] and 3:-1:1 which gives [3 2 1]. You should now be able to see which elements these expressions correspond to in the matrix. It is perfectly acceptable to combine matrices: however we need to make sure that the operation is well defined within MATLAB. This usually involves ensuring that the matrix (or vectors) involved have the correct dimensions for the operation to proceed.
