Answer 1

Core answer

The textscan function was added to Octave in version 3.4.0, which was released in February 2011. Your best option, then, is to install a newer version of Octave. If, for some reason, that is not an option you could try using fscanf (as suggested here).

History

The textscan function is not mentioned in the new function list in the version 3.4 release news, but textscan.m is not present in the version 3.2.4 distribution.

It appears to have been added as a result of this ticket (scroll to the bottom of the ticket), which was created as a result of this request.
