+\item All modified functions except SampleLin and Sample
+yield results that precisely match 
+\begin{itemize}
+\item Some functions fell extremely close in accuracy to 
+the original, and were considered to 'pass'
+\item The average of 1000 SampleLin tests deviated from the 
+average of 1000 tests of the original with an error of 0.01 
+\end{itemize}  
+\item The system tests differ if the number of nentries is 
+greater than 500; if not however the results of the system 
+test conform.

+\frametitle{Accuracy Discussion}
+\begin{itemize}
+\item The deviations in SampleLin and Sample can be 
+attributed to the functions use of random numbers
+\item The negligable deviations in other ported functions 
+are likely attributed to differences in CPU and GPU 
+arithmetic, leading to different round-off errors
