CsxSort() Sub CsxSort ( N As  Long, Val() As  Double, Ptr() As  Long, Ind() As  Long, Optional Info As  Long, Optional Base As  Long = -1  ) Sort elements of sparse matrix (CSC/CSR) Purpose This function sorts the elements of sparse matrix in CSC or CSR format within each column (if CSC) or row (if CSR). Parameters [in] N Number of columns (if CSC) or rows (if CSR) of the matrix. (N >= 0) (If N = 0, returns without computation) [in] Val() Array Val(LVal - 1) (LVal >= Nnz) (Nnz is the number of nonzero elements of the matrix) Values of nonzero elements of the matrix. [in] Ptr() Array Ptr(LPtr - 1) (LPtr >= N + 1) Column pointers (if CSC) or row pointers (if CSR) of the matrix. [in] Ind() Array Ind(LInd - 1) (LInd >= Nnz) Row indices (if CSC) or column indices (if CSR) of the matrix. [out] Info (Optional) = 0: Successful exit. = i < 0: The (-i)-th argument is invalid. [in] Base (Optional) Indexing of Ptr() and Ind(). = 0: Zero-based (C style) indexing: Starting index is 0. = 1: One-based (Fortran style) indexing: Starting index is 1. (default: Assumes 1 if Ptr(0) = 1, 0 otherwise)
