The squared \index{Matrix Norm!Frebenius norm}Frobenius norm of a matrix
$\Abf_{m\times n}$ is defined as
\nomenclature{$\norm{\Abf}_F$}{Frobenius norm of $\Abf$}
\begin{equation*}
  \norm{\Abf}_F^2 = \sum_{i=1}^m\sum_{j=1}^na_{ij}^2 =
  \trace(\trans\Abf\Abf).
\end{equation*}
 
The 2-norm\index{Matrix Norm!2-norm} of a matrix $\Abf_{m\times n}$ is
defined as\nomenclature{$\norm{\Abf}_2$}{2-norm of $\Abf$}
\begin{equation*}
\norm{\Abf}_2 = \max_{\norm{\xbf}_2=1}\norm{\Abf\xbf}_2\quad
\text{for $\xbf\in\Rbb^{n\times 1}$}
\end{equation*}
 
For a subspace $\Vcal\subseteq \Rbb^n$ and a vector $\ubf\in\Rbb^n$,
let $\proj{\Vcal}{\ubf}$
\nomenclature{$\proj{\Vcal}{\ubf}$}{Projection of $\ubf$ onto subspace $\Vcal$}
\index{Projection}
be the projection of $\ubf$ onto $\Vcal$.
If $\{\vbf_1,...,\vbf_k\}$ is a basis for $\Vcal$, then
\begin{equation*}
  \proj{\Vcal}{\ubf} = \sum_{i=1}^k \bkt{\vbf_i,\ubf}\vbf_i
