Re: Compiling octave with MSVC

[Alois Schloegl]

Hi Micheal,


your result is about speed. Could you also check the accuracy of the 
results?

I suggest this test:  http://www.dpmi.tu-graz.ac.at/~schloegl/matlab/fermat/
Download these files into a local directory
http://www.dpmi.tu-graz.ac.at/~schloegl/matlab/fermat/fermat.m
http://www.dpmi.tu-graz.ac.at/~schloegl/matlab/fermat/flttest.m
http://www.dpmi.tu-graz.ac.at/~schloegl/matlab/fermat/flttest1000.m
and run flttest and flttest1000. Please send the resulting  *.txt files.
