+A study of the codec2 700C Rate K resampler
+
+# Basic setup:
+
+```
+$ sudo apt install texmaker texlive-bibtex-extra
+$ texmaker ratek_resampler.tex &
+```
+
+1. Options -> Config Texmaker -> Quick Build -> select 2nd option: "PDFLatex+BibLatex+PDFLatex2+ViewPDF"
+1. Open `ratek_resampler.tex`
+1. F1 to build document.
+
+# Latex/EPS figures from Octave:
+
+Gotchas:
+1. Watch out for any control characters like & or _ in figure text, this will cause the build step to choke.
+1. In `/path/to/ratek_resampler` Optionally clean out any older .eps files of same name (e.g. previously rendered with encapsulated Postscript).
+1. In texmaker, build PDF from `ratek_resampler.tex`, not the figure `.tex` file (e.g. testepslatex.tex), you might end up in the latter if an error was encountered.
+
+For nice rendering on your monitor, there may be some non-standard font and line size defaults set up in `.octaverc`, e.g.:
+```
+set(0, "defaulttextfontsize", 24)  % title
+set(0, "defaultaxesfontsize", 24)  % axes labels
+set(0, "defaultlinelinewidth", 2)
+```
+For Latex/EPS plots, save these defaults, and set up fontsize 10, line size 0.5 before plotting:
+
+```
+textfontsize = get(0,"defaulttextfontsize");
+linewidth = get(0,"defaultlinelinewidth");
+set(0, "defaulttextfontsize", 10);
+set(0, "defaultaxesfontsize", 10);
+set(0, "defaultlinelinewidth", 0.5);
+```
+
+Render your figure then print in EPS Latex using:
+
+```
+octave:1> print("testepslatex","-depslatex","-S300,300");
+```
+
+After plotting, the defaults can be restored:
+
+```
+set(0, "defaulttextfontsize", textfontsize);
+set(0, "defaultaxesfontsize", textfontsize);
+set(0, "defaultlinelinewidth", linewidth);
+```
+
+Latex code to insert figure:
+```
+\begin{figure}[h]
+\caption{Test Octave -depslatex}
+\begin{center}
+\input testepslatex.tex
+\end{center}
+\end{figure}
+```
