Detailed Description

Test of StdLinearOperator, its inverse and transpose.

\( A=\begin{pmatrix} 4 & 1 \\ 2 & 3 \end{pmatrix},\quad A^{-1}=\frac{1}{10}\begin{pmatrix} 4 & -1 \\ -2 & 3 \end{pmatrix} \)

1) Compute \(b\) in \(Ax = b\), when \( x=\begin{pmatrix} 1 \\ -1 \end{pmatrix}\)

2) Solve for \(x\) in the above when \(b=\begin{pmatrix} 3 \\ -1 \end{pmatrix}\)

3) Compute \(c\) in \(A^\top y=c\) when \(y=\begin{pmatrix} -2 \\ 1 \end{pmatrix}\)

4) Solve for \(y\) in the above when \(c=\begin{pmatrix} -6 \\ 1 \end{pmatrix}\)

Also ensure that the interface works with both ROL::Vector and std::vector arguments
