[LON-CAPA-users] tex(maxima_expression)

[Gerd Kortemeyer]

Hi,

You can also use the tex1()-command in MAXIMA,

$texformula=&cas('maxima',"tex1($formula)");

The output is in inline-format, and I don't like the way it renders fractions, so the coming lines fix that:

$texformula=~s/\\\\/\\/gs;
$texformula=~s/^\"//;
$texformula=~s/\"$//;
$texformula=~s/\{([^\{]+)\}\\over\{([^\}]+)\}/\\frac\{$1\}\{$2\}/gs;

and then

<m eval="on" display="mimetex">\[$texformula\]</m>

I might package that into a convenient function call later.

- Gerd.
