Hello all,

Is there any way to implement an algorithm on cvx to compute the unitary vectors at which a given matrix attains its norm? That is, we want to solve on cvx the following problem:

\begin{equation*}

\left{\begin{arrray}{l} \max |A x| \ |x|=1 \end{array} \right}

\end{equation*}

Thanks in advanced.

Clemente
