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)$
