Functions should have help text so that people know how to use it.


This is the prefered format for help text. There is also a comprehensive TexInfo manual.

Octave specific macros


Do not use this macro empty as it will create problems with the generate_html package.




Use this to include literal text. Special useful to insert formulas.

           E[Z(i,k) ]
IRL(k) =  ------------
@end verbatim


Do not use the example environment to insert formulas, consider using @verbatim instead

Special inserts

Escape characters

To escape characters in TexInfo, use the character @. Only the characters @, { and } need to be escaped.

  • @@ stands for a single @ (do not put braces after an @@ command)
  • @{ stands for a single {
  • @} stands for a single }

In certain contexts (such as @acronym or @xref), commas may need to be escaped. In such situations, use @comma{}.

Ellipsis (...)

Ellipsis are frequently used in octave help text, specially when defining a function API. Use the @dots{} rather than three dots.

@deftypefn {Function File} {} imhist (@var{I})
@deftypefnx {Function File} {[@var{counts}, @var{x}] =} imhist (@dots{})
