Hi all,
How do I solve large sparse systems of equations in scipy.
Assume that the coefficient matrix is given in MatrixMarket format.
Which package is currently used in scipy (Super-LU, UMFPACK) ?
How do I multiply a sparse matrix with a vector ?
Can I use complex matrices ?
How do I generate a bordered matrix in sparse format
e.g. [A , x; x^H , 0]
A small example would be appreciated.
Nils
