1. (10 pts) For a square matrix A € Rnxn, let Aij denote its entry at (i,j) position. Entries Aji are called diagonal entries of A, e..., A11, A22, ..; The sum of all diagonal entries of A is called the trace of Ă, often denoted as tr(A) or trace(A). Find tr(A) and A31 for the following matrix: A= ( 1 2 3 -1 10 0 0 1 -5
