[SciPy-user] dstevx not implemented
Sun Sep 2 10:57:31 CDT 2007
Good morning to all,
I just started tinkering with SciPy, and it looks very interesting.
However, I have a question and the searches I performed on the mailing
list or the web returned nothing valuable.
I want to find some of the eigenvalues and eigenvectors of a quite large
tridiagonal matrix (around 20000x20000, maybe more). I used to do this
task in fortran using dstevx, but I noted that this function is not
exported to python, according to a comment in flapack_esv.pyf.src .
I would like to ask is:
- is this is due to technical or human-resources issues?
- If any other of you had my same need, how did you solve the problem so
to have an efficient code?
Thanks in advance
