Web14 Jul 2024 · For multiplying two matrices of size n x n, we make 8 recursive calls above, each on a matrix/subproblem with size n/2 x n/2. Each of these recursive calls multiplies two n/2 x n/2 matrices, which are then added together. For addition, we add two matrices of size. n2 4 n 2 4, so each addition takes Θ( n2 4) Θ ( n 2 4) time.
