If I have an array N:
N = Numeric.zeros((1000,), Numeric.Float) repr(N.__copy__) '<built-in method __copy__ of array object at 0x00809F00>'
What is the actual address of the first element? Or, as an offset from the object? numarray gives us that:
N = numarray.zeros((1000,), numarray.Float) N.info() class: <class 'numarray.numarraycore.NumArray'> shape: (1000,) strides: (8,) byteoffset: 0 bytestride: 8 itemsize: 8 aligned: 1 contiguous: 1 data: <memory at 009d67b8 with size:8000 held by object 009d6798 aliasing object 00000000> byteorder: little byteswap: 0 type: Float64
In numarray, the offset appears to be 20. If I try to use memmove() to fill a Numeric array it faults when using an offset of 20... Ray
