PetscErrorCode LMESetRHS(LME lme,Mat C)
Collective
Input Parameters
| lme | - the matrix function context
|
| C | - the right-hand side matrix

Notes
The matrix equation takes the general form A*X*E+D*X*B=C, where matrix C is
given with this function. C must be a low-rank matrix of type MATLRC, that is,
C = U*D*V' where D is diagonal of order k, and U, V are dense tall-skinny
matrices with k columns. No sparse matrix must be provided when creating the
MATLRC matrix.
In equation types that require C to be symmetric, such as Lyapunov, C must be
created with V=U (or V=NULL).
