Thanks but it still doesn't work:
import numpy
import scipy.weave
from scipy.weave import converters
def my_sum(a):
n=int(len(a))
code="""
int i;
long int counter;
counter =0;
for(i=0;i<n;i++){
counter=counter+a(i);
}
return_val=counter;
"""
err=scipy.weave.inline(code,['a','n'],type_converters=scipy.weave.converters.blitz,compiler='gcc')
return err
a=numpy.array(range(60000))
time my_sum(a)
time sum(range(60000))
(I needed to use scipy.weave instead of weave everywhere, sage ignored the
"import scipy.weave" hm.....)
gives:
