The correct way to do this is to, either:
In your C code check PyArray_IS_C_CO
Hi,
In part of my C++ code, I often do
void foo(PyObject * matrix) {
do stuff
}
where matrix is a numpy mxn matrix created on the Python side, where
foo() eg. is invoked as
a = numpy.array([[1,2],[3,5]])
foo(a)
However, if you call transpose() on a, some care should be taken, since
