[SciPy-User] solve_banded usage (once again) (Wagner Sebastian)

[Wagner Sebastian]

Hi Federico,

Some days after posting it in beginning of Sept, I found it out. Maybe I can improve the doc in October or provide a conversion function for scipy.sparse.dia

And I were also digging in the Python-Code but it only wraps the Fortran-Function, and the Fortran help itself also is very qiet.

Hey Wagner,

not sure how helpful this is, but if you dig into the SciPy source code, you'll see that solve_banded is a fairly thin wrapper around the gbsv function from lapack.

If you go look at the lapack source code:

http://software.intel.com/sites/products/documentation/hpc/mkl/mklman/GUID-36E347A0-A1DF-48F0-A554-A98A3704A3B5.htm

You can get a better idea of the parameters there.

Not sure if this is helpful - I've never really had to use that function myself, but at least it might give you some pointers.

Federico
