* where "DATA_TYPE" is any type supported by the NumPy module, and
* "DIM_TYPE" is any int-like type suitable for specifying dimensions.
* The difference between "ARRAY" typemaps and "FARRAY" typemaps is
* that the "FARRAY" typemaps expect Fortran ordering of
* multidimensional arrays. In python, the dimensions will not need
* to be specified (except for the "DATA_TYPE* ARGOUT_ARRAY1"
* typemaps). The IN_ARRAYs can be a numpy array or any sequence that
* can be converted to a numpy array of the specified type. The
* INPLACE_ARRAYs must be numpy arrays of the appropriate type. The
* ARGOUT_ARRAYs will be returned as new numpy arrays of the
* appropriate type.
*
* These typemaps can be applied to existing functions using the
* %apply directive. For example:
*
* %apply (double* IN_ARRAY1, int DIM1) {(double* series, int length)};
* double prod(double* series, int length);
*
* %apply (int DIM1, int DIM2, double* INPLACE_ARRAY2)
* {(int rows, int cols, double* matrix )};
* void floor(int rows, int cols, double* matrix, double f);
*
* %apply (double IN_ARRAY3[ANY][ANY][ANY])
* {(double tensor[2][2][2] )};
* %apply (double ARGOUT_ARRAY3[ANY][ANY][ANY])
* {(double low[2][2][2] )};
* %apply (double ARGOUT_ARRAY3[ANY][ANY][ANY])
* {(double upp[2][2][2] )};
* void luSplit(double tensor[2][2][2],
* double low[2][2][2],
* double upp[2][2][2] );
*
* or directly with
*
* double prod(double* IN_ARRAY1, int DIM1);
*
* void floor(int DIM1, int DIM2, double* INPLACE_ARRAY2, double f);
*
* void luSplit(double IN_ARRAY3[ANY][ANY][ANY],
* double ARGOUT_ARRAY3[ANY][ANY][ANY],
* double ARGOUT_ARRAY3[ANY][ANY][ANY]);
