Dirk and Paul,
While we at it. Could someone explain it to me why Dirk's randmt is few times
faster than the randn from octave-forge?
octave:2> tic ; randmt(1000); toc
ans = 0.055763
octave:3> tic ; randmt(3000); toc
ans = 0.77237
octave:4> tic ; randmt(10000); toc
ans = 26.469
octave:5> tic ; randn(1000); toc
ans = 0.31140
octave:6> tic ; randn(3000); toc
ans = 2.7659
octave:7> tic ; randn(10000); toc
ans = 30.786
((( It does seem that times converge for very large arrays...)))
octave:8> which randn
randn is the dynamically-linked function from the file
/usr/local/libexec/octave/2.1.50/site/oct/i686-pc-linux-gnu/octave-forge/randn.oct
Sincerely,
Dmitri.
