Well, it is for the experienced (a relatively simple task, that is), but
the question is "why do you have to do so?" instead of there being the
facility in the base formatted i/o functions? Plus, the time taken for
doing that could be used for other more useful things.
I have had in the past some mex files that did precisely that--pass
FORMAT strings to Fortran to handle some i/o. Unfortunately, the source
seems to have been lost on the machine at a former place of employment
as I haven't been able to find it here. The question came up not very
long ago w/ a poster who had the identical question regarding an input
string similar to the example. It is conceptually quite simple; in
practice as I recall it took some effort to make it general-enough to be
of much generic use.
At this point in my life I'm not sure I'll ever have the ambition to
actually do that much "real" coding again--I've simply lost the
ambition/drive to write code at 2AM like a young'un and am too involved
in the farming operation and other activities at the local level to have
the time for more than just poking around at cssm for a little while in
the mornings to sorta' halfway keep my hand in...
But, that TMW doesn't do it doesn't mean it's not a good idea to include
in Matlab. :)
Since TMW has been kind enough to me recently to provide a license for
R2012b for evaluation/comments, perhaps I will try to build a coherent
set of enhancement requests, though...
It's just a shame that K&R didn't follow the clearly better path already
laid out instead of having to reinvent a (slightly out-of-round) wheel
and so we have to suffer for it...
