Hi all,
I would like to solve
K_dyn x = f,
where K_dyn is a sparse matrix. UMFPACK is not installed and I am using
the latest svn version.
>>> K_dyn
<71987x71987 sparse matrix of type '<type 'numpy.float64'>'
with 3083884 stored elements (space for 3083884)
in Compressed Sparse Column format>
>>> f
<71987x1 sparse matrix of type '<type 'numpy.float64'>'
with 52 stored elements (space for 52)
in Compressed Sparse Column format>
>>> x = spsolve(K_dyn, f)
Traceback (most recent call last):
File "<stdin>", line 1, in ?
File
"/usr/local/lib64/python2.4/site-packages/scipy/linsolve/linsolve.py",
line 75, in spsolve
b = asarray(b, dtype=data.dtype)
File "/usr/local/lib64/python2.4/site-packages/numpy/core/numeric.py",
line 132, in asarray
return array(a, dtype, copy=False, order=order)
ValueError: setting an array element with a sequence.
Is this a bug ?
