ENH preserver contiguous property
The a[:,np.newaxis] operation does not preserve contiguousity, so we shift to
reshape which preserve this one. For an example see below:
In [1]: import numpy as np
In [2]: np.__version__
Out[2]: '1.6.2'
In [3]: a = np.array([1,2,3])
In [4]: a.flags
Out[4]:
C_CONTIGUOUS : True
F_CONTIGUOUS : True
OWNDATA : True
WRITEABLE : True
ALIGNED : True
UPDATEIFCOPY : False
In [5]: a[:,np.newaxis].flags
Out[5]:
C_CONTIGUOUS : False
F_CONTIGUOUS : False
OWNDATA : False
WRITEABLE : True
ALIGNED : True
UPDATEIFCOPY : False
In [6]: a.reshape(-1,1).flags
Out[6]:
C_CONTIGUOUS : True
F_CONTIGUOUS : False
OWNDATA : False
WRITEABLE : True
ALIGNED : True
UPDATEIFCOPY : False
