Distribute or not? suppose you need to compute z = (a + b)(x + y), where a and b are m × n matrices and x and y are n-vectors. (a) what is the approximate flop count if you evaluate z as expressed, i. e., by adding a and b, adding x and y, and then carrying out the matrix-vector multiplication? (b) what is the approximate flop count if you evaluate z as z = ax + ay + bx + by, i. e., with four matrix-vector multiplies and three vector additions?
