ZCsrCoo() Sub ZCsrCoo ( M As  Long, N As  Long, Val() As  Complex, Rowptr() As  Long, Colind() As  Long, Val2() As  Complex, Rowind2() As  Long, Colind2() As  Long, Optional Info As  Long, Optional Nnz As  Long, Optional Base As  Long = -1, Optional Base2 As  Long = 0  ) CSR -> COO (Complex matrices) Purpose This function converts the sparse matrix in CSR format to the sparse matrix in COO format. The element order within row is same as reading order. Parameters [in] M Number of rows of the matrix. (M >= 0) (If M = 0, returns without computation) [in] N Number of columns of the matrix. (N >= 0) (If N = 0, returns without computation) [in] Val() Array Val(LVal - 1) (LVal >= Nnz) Values of nonzero elements of input matrix. [in] Rowptr() Array Rowptr(LRowptr - 1) (LRowptr >= M + 1) Row pointers of input matrix. [in] Colind() Array Colind(LColind - 1) (LColind >= Nnz) Column indices of input matrix. [out] Val2() Array Val2(LVal2 - 1) (LVal2 >= Nnz) Values of nonzero elements of output matrix. [out] Rowind2() Array Rowind2(LRowind2 - 1) (LRowind2 >= Nnz) Row indices of output matrix. [out] Colind2() Array Colind2(LColind2 - 1) (LColind2 >= Nnz) Column indices of output matrix. [out] Info (Optional) = 0: Successful exit. = i < 0: The (-i)-th argument is invalid. [out] Nnz (Optional) Number of nonzero elements in the matrix. [in] Base (Optional) Indexing of Rowptr() and Colind(). = 0: Zero-based (C style) indexing: Starting index is 0. = 1: One-based (Fortran style) indexing: Starting index is 1. (default: Assumes 1 if Rowptr(0) = 1, 0 otherwise) [in] Base2 (Optional) Indexing of Rowind2() and Colind2(). (default = 0) = 0: Zero-based (C style) indexing: Starting index is 0. = 1: One-based (Fortran style) indexing: Starting index is 1.
