Hi all, Just now I have installed pysparse via http://people.web.psi.ch/geus/pyfemax/download.html. It works fine for me ! Is it possible to convert matrices from the pysparse specific format into a format such that I can visualize them with pylab.spy ?
type(A) <type 'sss_mat'>
from pylab import spy, show spy(A) Traceback (most recent call last): File "<stdin>", line 1, in ? File "/usr/lib64/python2.4/site-packages/matplotlib/pylab.py", line 2281, in spy ret = gca().spy(*args, **kwargs) File "/usr/lib64/python2.4/site-packages/matplotlib/axes.py", line 5089, in spy nr, nc = Z.shape ValueError: need more than 0 values to unpack
I have used the following example from the website from pysparse import itsolvers, poisson, precon, jdsym A = poisson.poisson2d_sym(200).to_sss() K = precon.ssor(A) k_conv, lmbd, Q, it, it_inner = \ jdsym.jdsym(A, None, K, 5, 0.0, 1e-10, 150, itsolvers.qmrs, clvl=1) Nils
