scikits.umfpack.spsolve(A, b)

Solve the sparse linear system Ax=b, where b may be a vector or a matrix.

Parameters:

Andarray or sparse matrix

The square matrix A will be converted into CSC or CSR form

bndarray or sparse matrix

The matrix or vector representing the right hand side of the equation.

Returns:

xndarray or sparse matrix

the solution of the sparse linear equation. If b is a vector, then x is a vector of size A.shape[0] If b is a matrix, then x is a matrix of size (A.shape[0],)+b.shape[1:]
