Quick LaTeX Tutorial

1. Quick LaTeX Tutorial

2. LaTeX Tutorial • Why do you want to learn LaTeX? • Nuts and Bolts of LaTex • Examples

3. Why you want to learn LaTeX • Very powerful control of document generation, particularly large technical documents • Minimizes the drudgery of formatting, numbering, and referencing • Disadvantage: • Steep Learning Curve

4. LaTeX Platforms • Scientific Workplace • (Commercial Package) • UNIX Systems (LyX) • (Free) • MikTex and WinEdt • PC Shareware

5. LaTeX Resources • http://www.ctan.org • http://www.colorado.edu/ITS/docs/latex/Ref/ • The Not So Short Introduction to LaTeX 2e (Tobias Oetiker) • Math Into LaTeX (George Gratzer)

6. The LaTeX Process • Create a text file (with your favorite text editor) with LaTeX commands • “Compile” or “Build” your document using the LaTeX program • Display resulting Document • Continue writing and go to 1 until finished • Convert Document to Postscript or PDF

7. Flow of LaTeX Process

8. Source code of your first LaTeX document(fish.tex) \documentclass{article} \begin{document} My mother is a fish. \end{document}

9. To use xdvi viewer % latex fish.tex … % xdvi fish.dvi To use acroread % pdflatex fish.tex … % acroread fish.pdf Commands to Build and View Document

11. Emphasizing words(fish.tex) \documentclass{article} \begin{document} \emph{My mother} is a fish. \end{document}

13. Underlining words(fish.tex) \documentclass{article} \begin{document} \emph{My mother} is a \underline{fish}. \end{document}

15. Making references in LaTeX(fish.tex) \documentclass{article} \begin{document} \emph{My mother} is a \underline{fish} \cite{WF}. \begin{thebibliography}{99} \bibitem{WF} William Falkner, \emph{As I Lay Dying} \end{thebibliography} \end{document}

16. Need to compile the document twice • Because we are using symbolic references, e.g., \cite{WF}, a second pass is necessary • The second pass will resolve references

18. Sum Equation Example(sum.tex) \documentclass{article} \begin{document} \begin{equation} \label{E:sum} s = \sum_{i=1}^{n}x_{i} \end{equation} \end{document}

20. Sum of Squares Equation Example (sum_squares.tex) \documentclass{article} \begin{document} \begin{equation} \label{E:sum_squares} s2 = \sum_{i=1}^{n}x_{i}^{2} \end{equation} \end{document}

22. Mean Equation Example(mean.tex) \documentclass{article} \begin{document} \begin{equation} \label{E:mean} \bar{x} = \frac{\sum_{i=1}^{n}x_{i}} {n} \end{equation} \end{document}

24. Mean Equation Examplewith limits (mean_limits.tex) \documentclass{article} \begin{document} \begin{equation} \label{E:mean} \bar{x} = \frac{\sum\limits_{i=1}^{n} x_{i}} {n} \end{equation} \end{document}

26. Variance Equation Example (variance.tex) \documentclass{article} \begin{document} \begin{equation} \label{E:variance} \sigma^{2} = \frac{\sum\limits_{i=1}^{n} \left(x_{i} - \bar{x}\right)^{2}} {n-1} \end{equation} \end{document}

28. Standard Deviation Equation Example (sd.tex) \documentclass{report} \begin{document} \chapter{Standard Deviation} \begin{equation} \label{E:sd} \sigma = \sqrt{\frac{\sum\limits_{i=1}^{n} \left(x_{i} - \bar{x}\right)^{2}} {n-1}} \end{equation} \end{document}

30. Changing the document styles \documentclass{article} \documentclass{book} \documentclass{letter} \documentclass{report}

31. Report document style(main.tex) \documentclass{report} \title{Assignment 2 for SIMG726} \author{Rolando V. Raque\~no} \begin{document} \maketitle \tableofcontents \end{document}

33. Create the following chapters chapter_sum.tex chapter_mean.tex chapter_sd.tex

34. chapter_mean.tex \chapter{Mean} \label{C:Mean} \begin{equation} \label{E:mean} \bar{x} = \frac{\sum_{i=1}^{n}x_{i}} {n} \end{equation}

35. chapter_sum.tex \chapter{Sum} \label{C:Sum} \begin{equation} \label{E:sum} s = \sum_{i=1}^{n}x_{i} \end{equation}

36. chapter_sd.tex \chapter{Standard Deviation} \label{C:SD} \begin{equation} \label{E:sd} \sigma = \sqrt{\frac{\sum\limits_{i=1}^{n} \left(x_{i} - \bar{x}\right)^{2}} {n-1}} \end{equation}

37. Modify main.tex to include chapters \documentclass{report} \title{Assignment 2 for SIMG726} \author{Rolando V. Raque\~no} \begin{document} \maketitle \tableofcontents \include{chapter_sum} \include{chapter_mean} \include{chapter_sd} \end{document}

39. Modify chapter_sd.tex \chapter{Standard Deviation} \label{C:SD} … \end{equation} We can see that equation \ref{E:sd} uses equation \ref{E:mean} to compute the mean and that the \emph{Mean} function uses equation \ref{E:sum} both of which are defined in Chapter \ref{C:Sum} and \ref{C:Mean}, respectively

41. Modify main.tex to include chapters \documentclass{report} \title{Assignment 2 for SIMG726} \author{Rolando V. Raque\~no} \begin{document} \maketitle \tableofcontents \include{chapter_mean} \include{chapter_sum} \include{chapter_sd} \end{document}

43. Including image graphics into you LaTeX document • Need to convert your image graphics into EPS (encapsulated postscript). • For images, use pnmtops, e.g. % pnmtops MyCat.pgm > MyCat.ps • Need to include an extension package to LaTeX called “graphics” using command \usepackage{graphics} • N.B. In CIS systems, following example works for latex but not for pdflatex

44. Image Graphics Example(image.tex) \documentclass{article} \usepackage{graphics} \begin{document} \begin{figure} \includegraphics{MyCat.ps} \caption{This is My Cat} \label{F:MyCat} \end{figure} \end{document}
