Does someone have an example of using SWIG to connect Numeric arrays to C code that expects double* arguments?

Hi Paul, I have a fairly comprehensive set of typedefs (including 1-D and 2-D array input and output) for interfacing Numeric arrays here: ftp://cfa-ftp.harvard.edu/pub/ransom/numpy.i As an example, say you have a function with a prototype: int foo(double *array, int len_array); You would simply make a ".i" file with the following: ====================== %module foo %include numpy.i %apply double* IN_1D_DOUBLE { double *array }; int bar(double *array, int len_array); ======================= Run swig on it, compile it, and import it.
