Unit 2.2.2 Haven't we seen this before?

We already employed various cases of blocked matrix-matrix multiplication in Section 1.3.

Homework 2.2.2.1.

In Section 1.3, we already used the blocking of matrices to cast matrix-matrix multiplications in terms of dot products and axpy operations. This is captured in

Figure 2.2.5. Click here to enlarge.

For each of partitionings in the right column, indicate how \(m_b \text{,}\) \(n_b \text{,}\) and \(k_b \) are chosen.

Homework 2.2.2.2.

In Section 1.3 and Section 1.4, we also already used the blocking of matrices to cast matrix-matrix multiplications in terms of matrix-vector multiplication and rank-1 updates. This is captured in
