Typemaps are keyed off a list of one or more function arguments,Įither by type or by type and name. SWIG interface file would need the following: To obtain the Python interface discussed above, your That the rms function prototype defined above was in a header file Of typemaps intended to make the type of array-related conversionsĭescribed above relatively simple to implement. How to use numpy.i, a SWIG interface file that defines a series

SWIG allows these types of conversions to be defined via a Internally convert it to a NumPy array before extracting its data Itself could be a nearly arbitrary sequence (so long as each elementĬan be converted to a double) and the wrapper code would Even better, since NumPy supportsĬonstruction of arrays from arbitrary Python sequences, seq Length n would be extracted from seq internally before being Where seq would be a NumPy array of double values, and its Def rms ( seq ): ''' rms: return the root mean square of a sequence rms(numpy.ndarray) -> double rms(list) -> double rms(tuple) -> double '''
