Question: (2) An N × N Matrix A Is Strictly Upper Triangular If A,J = 0 For All I > J. It goes like this: the triangular matrix is a square matrix where all elements below the main diagonal are zero. UpperTriangularize [m, k] replaces with zeros only the elements below the k subdiagonal of m. Details. Since the matrix A is symmetric positive definite, we can decompose it into a diagonal matrix [D.sub.A], a strictly lower triangular matrix [L.sub.A] , and a strictly upper triangular matrix [L.sup.H.sub.A]. If the entries on the main diagonal of a (upper or lower) triangular matrix are all 1, the matrix is called (upper or lower) unitriangular. Hints help you try the next step on your own.
