I am trying to import a big text file containing non-sparse 2D
numerical data into Mathematica. My aim is to get an array where the
numbers are stored as machine-precision numbers. In other words,

Flipping axes on Graphics242 (3/12/2009 7:20:06 AM) comp.soft-sys.math.mathematica Dear all,
I am looking for a way to flip the direction of an axis that is used

Up-to-dateness of the c.l.c. FAQ4136 (2/2/2004 11:32:30 PM) comp.lang.c Hi all, Isn't it time for an update of the wording in some sections of the c.l.c. FAQ ? The last update has been in 1999, I think, and quite a bit that has happened since then should probably be addressed (... Sidney
Extent of the "as-if" rule14433 (1/19/2004 7:58:34 AM) comp.lang.c Hi all, In a discussion with Tak-Shing Chan the question came up whether the as-if rule can cover I/O functions. Basically, he maintains it can, and I think it doesn't. Consider two programs: /*** a.c ***... Sidney
memcmp() semantics634 (11/23/2003 2:47:40 AM) comp.lang.c Hi all, Just browsing through my newly-acquired C99 spec, I was reading on the memcmp() function (7.21.4.1). It has a rather peculiar wording: int memcmp(const void *s1, const void *s2, size_t n); 1. The m... Sidney
