My first weave attempt weaves something to be desired.
test() works, but test2() doesn't.
It complains about the line "y = x(0,i);"
In function 'PyObject* compiled_func(PyObject*, PyObject*)':
blah.cpp:667: error: no match for call to '(py::object) (int, int&)'
I am no match for that error message. What am I doing wrong?
from scipy import weave
from scipy.weave import converters
import numpy.matlib as M
def test(i):
x = M.matrix([[1.0, 2.0, 3.0]]);
code = """
return_val = x(0,i);
"""
y = weave.inline(code, ['x', 'i'], type_converters=converters.blitz)
return y
def test2(i):
x = M.matrix([[1.0, 2.0, 3.0]]);
code = """
double y;
y = x(0,i);
return_val = y;
"""
y = weave.inline(code, ['x', 'i'], type_converters=converters.blitz)
return y
