Dear developers of Petsc and users,
I have the following numerical problem.
I need to solve the system Ax = B, where A is a square matrix, x and B
are rectangular matrix
The system is solved by doing LU decomposition.
In the next step I need to solve a system A'y = C, where A' is a complex
conjugate of A.
My question: is it possible to reuse the LU decomposition of A for doing
this?
Thank you,
Michael.
