Find AB by block multiplication of the matrices.
Find AB by block multiplication of the matrices.
$$A = \begin{bmatrix} 2 & -3 & -1 & 0 & -4 \ 1 & -5 & -2 & 3 & -1\ 0 & -4 & -2 & 7 & -1 \end{bmatrix}, \quad B = \begin{bmatrix} 6 & 4 \ 2 & -1 \ -3 & 7 \ 1 & 3 \ 5 & -3 \end{bmatrix}$$
[10]
$$A = \begin{bmatrix} 2 & -3 & -1 & 0 & -4 \ 1 & -5 & -2 & 3 & -1\ 0 & -4 & -2 & 7 & -1 \end{bmatrix}{3\times5}, \quad B = \begin{bmatrix} 6 & 4 \ 2 & -1 \ -3 & 7 \ 1 & 3 \ 5 & -3 \end{bmatrix}{5\times2}$$ Result $AB$ will be $3\times 2$. Split A columns after col 2 and col 4, rows after ro...
