\subsection{Detailed Description} Linear algebra utility functions, generally performed on matrices or vectors. This class is used to update the weight\+Vectors matrix according to the simple update rule as discussed by Rosenblatt\+: if a vector x has been incorrectly classified by a weight w, then w = w -\/ x and w\textquotesingle{}= w\textquotesingle{}+ x where w\textquotesingle{} is the weight vector which correctly classifies x. \subsection{Function Documentation} \mbox{\label{namespacemlpack_a7ce98127176182f568779d09912a28c9}} \index{mlpack@{mlpack}!Check\+Matrices@{Check\+Matrices}} \index{Check\+Matrices@{Check\+Matrices}!mlpack@{mlpack}} \subsubsection{Check\+Matrices()\hspace{0.1cm}{\footnotesize\ttfamily [1/3]}} {\footnotesize\ttfamily void Check\+Matrices (\begin{DoxyParamCaption}\item[{const arma\+::mat \&}]{x, }\item[{const arma\+::mat \&}]{xmlX, }\item[{const arma\+::mat \&}]{textX, }\item[{const arma\+::mat \&}]{binaryX }\end{DoxyParamCaption})} Referenced by Serialize\+Pointer\+Object\+All(). \mbox{\label{namespacemlpack_a324c6192b8e2844ebbdfbb8a86b208a8}} \index{mlpack@{mlpack}!Check\+Matrices@{Check\+Matrices}} \index{Check\+Matrices@{Check\+Matrices}!mlpack@{mlpack}} \subsubsection{Check\+Matrices()\hspace{0.1cm}{\footnotesize\ttfamily [2/3]}} {\footnotesize\ttfamily void Check\+Matrices (\begin{DoxyParamCaption}\item[{const arma\+::\+Mat$<$ size\+\_\+t $>$ \&}]{x, }\item[{const arma\+::\+Mat$<$ size\+\_\+t $>$ \&}]{xmlX, }\item[{const arma\+::\+Mat$<$ size\+\_\+t $>$ \&}]{textX, }\item[{const arma\+::\+Mat$<$ size\+\_\+t $>$ \&}]{binaryX }\end{DoxyParamCaption})} \mbox{\label{namespacemlpack_af06aeca3a4ac425303294bf3ccf46f1c}} \index{mlpack@{mlpack}!Check\+Matrices@{Check\+Matrices}} \index{Check\+Matrices@{Check\+Matrices}!mlpack@{mlpack}} \subsubsection{Check\+Matrices()\hspace{0.1cm}{\footnotesize\ttfamily [3/3]}} {\footnotesize\ttfamily void Check\+Matrices (\begin{DoxyParamCaption}\item[{const arma\+::cube \&}]{x, }\item[{const arma\+::cube \&}]{xmlX, }\item[{const arma\+::cube \&}]{textX, }\item[{const arma\+::cube \&}]{binaryX }\end{DoxyParamCaption})} \mbox{\label{namespacemlpack_ab0cc7f43ea0ea03a7654d61e7dea54e6}} \index{mlpack@{mlpack}!Get\+Memory@{Get\+Memory}} \index{Get\+Memory@{Get\+Memory}!mlpack@{mlpack}} \subsubsection{Get\+Memory()} {\footnotesize\ttfamily T\+::elem\+\_\+type$\ast$ mlpack\+::\+Get\+Memory (\begin{DoxyParamCaption}\item[{T \&}]{m }\end{DoxyParamCaption})\hspace{0.3cm}{\ttfamily [inline]}} Return the matrix\textquotesingle{}s allocated memory pointer, unless the matrix is using its internal preallocated memory, in which case we copy that and return a pointer to the memory we just made.
