\% Convert Matlab lessons published to latex to Octave form.

\% Usage: subbin.exe frommatlab.sub lessonNorg.tex lessonN.tex

\% Notes:
\%
\% 1) Matlab does not recognize all inline math.  This script will try
\% to correct.  To minimize conversion problems, make sure that inline
\% math does not contain any whitespace.
\%
\% 2) Matlab does not do <...> links; for <URL> it shows URL in
\% verbatim and for <URL TAG> it shows TAG in verbatim.  <URL> links
\% where URL starts with http will be fixed up.  <URL TAG> links can
\% obviously not be fixed, as the URL is gone.  You may want to put
\% the href in a <latex> environment or edit lessonN.tex when
\% otherwise OK.

\% A backslash starts commands in this file.  For a literal backslash,
\% double it.  The file format is:
\%
\%    ORIGINAL_TEXT
\%    REPLACEMENT_TEXT
\%
\%    ...

\% remove any control characters we want to use as markers
\(\ -\F\K\L\N-\Z\)
