For some reason numpy.linspace return an array with sage objects rather
than just floats. I am guessing it may be deeper than that. Numpy probably
uses sage types rather than converting to numpy types. The types of a[0]
to a[4] is strange, is there a sage type for floats? I mean I tried
numpy.linspace(0,2.0,6) and I got <type 'sage.rings.real_mpfr.RealNumber'>
for a[0] to a[4] and <type 'sage.rings.real_mpfr.RealLiteral'> for a[5].
Doing a cast numpy.array(a,dtype=float) returns something that will work.
