- X.flat returns an indexable 1-D iterator (mostly similar to an array
- but always 1-d) --- only has .copy and .__array__ attributes of an array!!!
-
- .typecode() --> .dtype.char
-
- .iscontiguous() --> .flags['CONTIGUOUS'] or .flags.contiguous
-
- .byteswapped() -> .byteswap()
-
- .itemsize() -> .itemsize
-
- .toscalar() -> .item()
-
- If you used typecode characters:
-
- 'c' -> 'S1' or 'c'
- 'b' -> 'B'
- '1' -> 'b'
- 's' -> 'h'
- 'w' -> 'H'
- 'u' -> 'I'
-
-
- C -level
-
- some API calls that used to take PyObject * now take PyArrayObject *
- (this should only cause warnings during compile and not actual problems).
- PyArray_Take
-
- These commands now return a buffer that must be freed once it is used
- using PyMemData_FREE(ptr);
-
- a->descr->zero --> PyArray_Zero(a)
- a->descr->one --> PyArray_One(a)
-
- Numeric/arrayobject.h --> numpy/oldnumeric.h
-
-
- # These will actually work and are defines for PyArray_BYTE,
- # but you really should change it in your code
- PyArray_CHAR --> PyArray_CHAR
- (or PyArray_STRING which is more flexible)
- PyArray_SBYTE --> PyArray_BYTE
-
- Any uses of character codes will need adjusting....
- use PyArray_XXXLTR where XXX is the name of the type.
-
-
- If you used function pointers directly (why did you do that?),
- the arguments have changed. Everything that was an int is now an intp.
- Also, arrayobjects should be passed in at the end.
-
- a->descr->cast[i](fromdata, fromstep, todata, tostep, n)
- a->descr->cast[i](fromdata, todata, n, PyArrayObject *in, PyArrayObject *out)
- anything but single-stepping is not supported by this function
- use the PyArray_CastXXXX functions.
