The above command takes the Mathematica matrix mat, converts it to L^ATEX, outputs the string and surrounding L^ATEX to a file, L^ATEXs the file and displays the L^ATEXed output to the screen using the program xdvi (this can be easily changed to other previewers such as dvipage or xpreview). This window contains the following formula in its display.

$$\pmatrix { a + b^T & c^{*} \cr d^{-1} & e \cr }$$

The L^ATEX file generated can be displayed by typing !!file.tex which produces

\documentstyle [12pt]{article} 
\begin{document} 
$$ 
\pmatrix { a + b^T & c^{*} \cr d^{-1} & e \cr }
$$ 
\end{document}

In[113]:= LookAtLongExpression[Sum[a[i],{i,1,50}]];

generates a window which contains the following formula in its display.

$$\displaylines{ a(1)+a(2)+a(3)+a(4)+a(5)+a(6)+a(7)+a(8)+ \cr a(9... ...(40)+a(41)+a(42)+a(43)+a(44)+a(45)+ \cr a(46)+a(47)+a(48)+a(49)+a(50) \cr }$$

The above examples in this chapter demonstrate the most commonly used features in NCAlgebra.
