a try/except clause, wouldn't it feel more "natural" to write "
np.equal(x, y)" ?

Python itself doesn't raise an exception in such cases :
>>> (3,4) != (2, 3, 4)
True
>>> (3,4) == (2, 3, 4)
False
Should numpy behave differently ?

Actually :
data=np.fromstring(f.read(), dtype=some_type, count=-1)

Hi all,
I've got some code which basically does :
f = open (path, 'rb')
header = f.read (some_length)
data = np.fromfile (f, dtype= some_type, count=-1)
In order to process compressed files, I switched the open sequence to :
if (plain):
f = open (path, 'rb')
else:
f

In the real case, it's a real 3-axes rotation
Dear all,
Can someone point me to a doc on dot product vectorisation ?
Here is what I try to do :
I've got a rotation function which looks like :
def rotat_scal(phi, V):
s = math.sin(phi)
c = math.cos(phi)
M = np.zeros((3, 3))
M[2, 2] = M[1, 1] = c
M[1, 2] = -s
M[2, 1
Hello,
I'm new to numpy, and considering using loadtxt() to read a data file.
As a starter, I tried the example of the doc page (
http://docs.scipy.org/doc/numpy/reference/generated/numpy.loadtxt.html) :
>>> from StringIO import StringIO # StringIO behaves like a file object
>>> c = Strin
