But all I could think of feels like such a kludge even before I start.
I mean, aside from having to loop over the lines (whereas fscanf
returns a nice matrix in a single command), I see:
-- Loadable Function: [...] = regexp (STR, PAT, OPTS, ...)
Regular expression string matching. Matches PAT in STR and returns
the position and matching substrings or empty values if there are
It looks to me like regexp will return a string, which has to be
turned into a number with str2double and such.
So I was hoping that there was something already nicely implemented,
like fscanf, except with regex matching capability. Is there such a
function (built-in or otherwise)?
