[SciPy-user] How to build a sparse block arrowhead matrix in scipy
Fri Jul 20 06:27:37 CDT 2007
what is the best way to build a sparse block arrowhead matrix A in scipy ?
The diagonal blocks are given by the matrices B1,B2,...,B8
The entries in the last block row/column are given by the matrix C.
The example is taken from .
A short python script would be appreciated.
