%% Find Bandwidth of Triangular Matrix %% % Create a 6-by-6 lower triangular matrix. A = tril(magic(6)) %% % Find the lower bandwidth of |A| by specifying |type| as |'lower'|. The % result is 5 since every diagonal below the main diagonal has nonzero % elements. B = bandwidth(A,'lower') %% % Find the upper bandwidth of |A| by specifying |type| as |'upper'|. The % result is 0 since there are no nonzero elements above the main diagonal. B = bandwidth(A,'upper')
