Let R be a complex upper triangular nxn matrix with . Show that
meaning that the modulus of all entries of approaches zero. Hint: We can write , for some positive real number and an upper triangular U > 0 matrix with zeros on the diagonal. Exercises 47 and 48 are helpful.
A triangular matrix with all components equal to below the main diagonal is called an upper triangular matrix. It's an element-based square matrix
