</P>
<P><FONT SIZE=3D2 FACE=3D"Arial">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 )</FONT></P>
<P><FONT SIZE=3D2 FACE=3D"Arial">if (!PyArray_Check($input)) {</FONT>
<BR><FONT SIZE=3D2 FACE=3D"Arial"> =
PyErr_SetString(PyExc_TypeError,"$1 is not a Numeric =
Array");</FONT>
<BR><FONT SIZE=3D2 FACE=3D"Arial"> return NULL;</FONT>
<BR><FONT SIZE=3D2 FACE=3D"Arial"> }</FONT>
</P>
<P><FONT SIZE=3D2 FACE=3D"Arial">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!</FONT></P>
<P><FONT SIZE=3D2 FACE=3D"Arial">thanks,</FONT>
