RE: [Numpy-discussion] Masked arrays in C extensions

[Paul F D. <pa...@pf...>]

Using the Python CAPI, you can get the MA module object, then from it =
the
function isMaskedArray(a), which you then can call with your argument a. =
You
can do the first two steps just once since they won't change.

Subject: [Numpy-discussion] Masked arrays in C extensions



Hi,=20

I'm writing a C exenstion which uses Masked Arrays.  Since a MA isn't a
'PyArray_Type', the PyArray_Check macro returns false, regular arrays =
work
fine.  ( from a SWIG typemap here )

if (!PyArray_Check($input)) {=20
    PyErr_SetString(PyExc_TypeError,"$1 is not a Numeric Array");=20
    return NULL;=20
  }=20

My question is how do I deal with Masked Arrays differently than regular
Array in the C code?  Any sample code would be greatly appreciated!

thanks,=20

P.S. this is Python2.2, Numeric-22=20
