Trying to wrap an existing library.
I managed to at least get started with a .spyx file as follows:
----------------------------------------
cdef extern from "stdlib.h":
void *malloc(size_t size)
int free(void*)
int sizeof()
cdef extern from "func.h":
int func( int n, float* x )
cdef double* d
def __cinit__(self):
self.d = <double*>malloc( sizeof(double))
self.n = 1
def __dealloc__(self):
free( self.d )
def func( self, data ):
cdef int i
self.n = len(data)
free( self.d )
self.d = <double*> malloc( self.n*sizeof(double) )
for i from 0 <= i < self.n:
self.d[i] = data[i]
func( self.n, self.d )
l = []
for i from 0 <= i < self.n:
l.append( d[i] )
return l
-------------------------
but this leaves much to be desired.
It should be a fairly standard operation
for which sage has good solutions.
Could someone please give me some pointers
as to how to improve the above?
