发帖数: 102 | 1 I tested them by sort a vector with the length 10000000.
I generated the vector by using the normal variable first, and
then sort it.
Here is the result by using gsl:
real 0m28.137s
user 0m23.945s
sys 0m0.284s
while it took only 5 seconds for the matlab to run.
Of course, this is only one of the tests. Has anyone done this before?
BTW:I am a big fan of the open source, but I really want to know which tools
is
more efficient for me.
Any comment is appreciated. | p*****e

didn't define NDEBUG, it will be much slower.
