[SciPy-user] weave.inline : resize an array in c++

[Samuel GARCIA]

I also try :
from scipy import *
from scipy import weave
from scipy.weave import converters

c = ones((3,6))

code = """
  PyArray_Dims dims;
  dims.len = 2;
  dims.ptr = new int[2];
  dims.ptr[0] = 4;
  dims.ptr[1] = 7;
  PyArray_Resize(c_array,&dims);
"""
err = weave.inline(code,
    ['c'],
    type_converters=converters.blitz)
print c


but fails again

Any ideas ?

Sam
