My name is Lucia Avalle. I am an electrochemist and a beginner in
"computational science". Sorry if I bother you, but I am trying to use fipy
and the followng error message was reported:
File "/home/lucia/FiPy-1.1/fipy/tools/sparseMatrix.py", line 45, in
<module>
import spmatrix
ImportError: No module named spmatrix
Thank you in advance
Lucia
