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
Find the pseudo inverses of the matrices

\begin{displaymath} A=(3 \ \ 4)\,, \qquad B=\left( \begin{array}{cc} 1 & 0\\ 2 & 2\\ 0 & 1\\ \end{array}\right) . \end{displaymath}

Solution:

$ A^+=\frac{1}{25}\left(\rule{0pt}{4ex}\right.$
$ \left.\rule{0pt}{4ex}\right)$ ,          $ B^+=\frac{1}{9}\left(\rule{0pt}{4ex}\right.$
$ \left.\rule{0pt}{4ex}\right)$
