## Unit2.2.2Haven't we seen this before?

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

###### Homework2.2.2.1.

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

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

###### Homework2.2.2.2.

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

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