ZCscIluSolve() Sub ZCscIluSolve ( ByVal Trans As  String, N As  Long, Val() As  Complex, Colptr() As  Long, Rowind() As  Long, D() As  Complex, B() As  Complex, X() As  Complex, Optional Info As  Long, Optional Base As  Long = -1  ) Incomplete LU decomposition (ILU) preconditioner (Complex matrices) (CSC) Purpose This routine is the incomplete LU decomposition preconditioner (ILU) for the sparse linear equations. It solves the equation M*x = b, M^T*x = b or M^H*x = b, where M is the preconditioner matrix. Parameters [in] Trans = "N": solve M*x = b. = "T": solve M^T*x = b. = "C": solve M^H*x = b. [in] N Dimension of preconditioner matrix. (N >= 0) (if N = 0, returns without computation) [in] Val() Array Val(LVal - 1) (LVal >= Nnz) (Nnz is number of non-zero elements) Values of non-zero elements of preconditioner matrix (lower triangular matrix L and upper triangular matrix U). [in] Colptr() Array Colptr(LColptr - 1) (LColptr >= N + 1) Column pointers of preconditioner matrix. [in] Rowind() Array Rowind(LRowind - 1) (LRowind >= Nnz) Row indices of preconditioner matrix. [in] D() Array D(LD) (LD >= N) The diagonal elements of upper triangular matrix U. [in] B() Array B(LB - 1) (LB >= N) Right hand side vector b. [out] X() Array X(LX - 1) (LX >= N) Solution vector x. [out] Info (Optional) = 0: Successful exit. = i < 0: The (-i)-th argument is invalid. [in] Base (Optional) Indexing of Colptr() and Rowind(). = 0: Zero-based (C style) indexing: Starting index is 0. = 1: One-based (Fortran style) indexing: Starting index is 1. (default: Assumes 1 if Colptr(0) = 1, 0 otherwise) Example Program See examples of ZCscIlu and ZCscIlu0.
