Problem

Recycle the matrices

A

and

B

from Exercise MISLE.C21 and set

\mathbf{c} = \begin{bmatrix} 2 \\ 1 \\ -3 \\ 2 \end{bmatrix} \qquad \mathbf{d} = \begin{bmatrix} 1 \\ 1 \\ 1 \\ 1 \end{bmatrix}

Employ the matrix

B

to solve the two linear systems

\mathcal{LS}(A, \mathbf{c})

and

\mathcal{LS}(A, \mathbf{d})
