A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
Solve the approximation problem $ \vert Ax-b\vert\longrightarrow\min$ with

$\displaystyle A=\left(\begin{array}{rr} -1 & 1\\ -1 & 2\\ 0 & -1\\ 0 & 1... ...) \,, \qquad b=\left( \begin{array}{r}-1\\ 0\\ 2\\ 0\\ 2\end{array}\right) \ . $

Solution:
$ x=\left(\rule{0pt}{4ex}\right.$
$ \left.\rule{0pt}{4ex}\right)$,          $ \vert Ax-b\vert^2=$ .
