Diagonal and Triangular Matrices is a part of the VCE Further Maths topic Matrices and subtopic Matrices and Their Applications. A diagonal matrix only has non-zero entries on the diagonal. This means every entry outside of the diagonal is 0. A triangular matrix has zeroes either above or below the diagonal.
