Hmm, this is weird:
{{{
sage: v = numpy.array([1,2,3,100000])
sage: m = diagonal_matrix(v)
---------------------------------------------------------------------------
TypeError Traceback (most recent call
last)
/mnt/usb1/scratch/drake/days27/sage-4.6.1.rc1/<ipython console> in
<module>()
/mnt/usb1/scratch/drake/days27/sage-4.6.1.rc1/local/lib/python2.6/site-
packages/sage/matrix/constructor.pyc in diagonal_matrix(arg0, arg1, arg2,
sparse)
1392 if str(entries.dtype).count('complex')==1:
1393 ring = CDF
-> 1394 v = [ring(x) for x in entries]
1395 else:
1396 raise TypeError('diagonal matrix entries are not a
supported type (list, tuple, vector, or NumPy array)')
TypeError: 'NoneType' object is not callable
}}}
Your examples seem to have all RDF entries; my example has numpy int64
entries. Do you see what's going on here?
