New issue 1381 by zorg724: error with mpmath documentation
http://code.google.com/p/sympy/issues/detail?id=1381
Exemple:
>>> mp.dps = 15
>>> print sumem(lambda n: 1/n**2, 1, inf)
>>> print sumem(lambda n: 1/n**2, 1, inf)
Traceback (most recent call last):
File "<interactive input>", line 1, in <module>
File "C:\fbtool\Python25\Lib\site-packages\mpmath\settings.py", line 130,
in g
v = f(*args, **kwargs)
File "C:\fbtool\Python25\Lib\site-packages\mpmath\calculus.py", line 448,
in sumem
a, b = AS_POINTS(interval)
TypeError: unpack non-sequence
http://docs.sympy.org/modules/mpmath/summation.html#euler-maclaurin-summation-sumem
The code shall be:
print sumem(lambda n: 1/n**2, [1, inf])
its seems that a lot of page of mpmath are KO (see Tanh-sinh quadrature
(quadts)ΒΆ, etc ..)
>>> print quadts(sin, 0, pi)
Traceback (most recent call last):
File "<interactive input>", line 1, in <module>
File "C:\fbtool\Python25\Lib\site-packages\mpmath\quadrature.py", line
428, in quadts
return quad(*args, **kwargs)
File "C:\fbtool\Python25\Lib\site-packages\mpmath\quadrature.py", line
390, in quad
points[0], prec, epsilon, m, verbose)
File "C:\fbtool\Python25\Lib\site-packages\mpmath\quadrature.py", line
119, in summation
for i in xrange(len(points)-1):
TypeError: object of type 'int' has no len()
the code shall be : >>> print quadts(sin, [0, pi])
2.0
the version used is:
>>> mpmath.__version__
'0.10'
