Re: [Fwd: compare the executive speed with Matlab]

[Michael Goffioul]

2 of your examples use for-loops. Octave if known to be
slower than Matlab with for-loops and it has been repeated
at many occasions. No wonder about the timing difference.
For the 3rd one, I'm not sure, it might be related to the
implementation of normcdf function.
