I followed the weave.inline example at http://www.scipy.org/PerformancePython which uses the C-like x(i,j) instead of the numpy x[i,j]. Changing test2 to y = x[0,i] gives "TypeError: cannot convert value to double" on the weave.inline line. > On 1/8/07, Keith Goodman <[EMAIL PROTECTED]> wrote: > > 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.
