Did you optimize your code using Nelder and Mead? i.e.
gcc myprogram myprogram.c -O4 -DHAVE_INLINE=1 -DGSL_RANGE_CHECK=0 \
-lgslcblas -lgsl

I'm not aware of any major difference -- could you submit a bug report
to [EMAIL PROTECTED] with an example program and the output compared
with MATLAB. Thanks.
