ssc_csc() void ssc_csc ( char  uplo, int  n, const double  val[], const int  colptr[], const int  rowind[], int  base, int  maxnnz2, double  val2[], int  colptr2[], int  rowind2[], int  base2, int *  info  ) SSC (CSC sparse matrix packed form) -> CSC (symmetric full matrix) Purpose This routine converts the symmetric CSC sparse matrix containing only upper or lower triangular elements to the general CSC sparse matrix containing all elements. The order of elements in each column of output matrix is same as that of input matrix (not to be sorted). The triangular elements (not including diagonal elements) other than specified by uplo in input matrix will be ignored if exist. Parameters [in] uplo Specifies whether the upper or lower triangular part of input matrix is stored. = 'U': Upper triangular part. = 'L': Lower triangular part. [in] n Number of rows and columns of matrix. (n >= 0) (if n = 0, returns without computation) [in] val[] Array val[lval] (lval >= nnz) (nnz is the number of nonzero elements of input matrix) Values of nonzero elements of input matrix. [in] colptr[] Array colptr[lcolptr] (lcolptr >= n + 1) Column pointers of input matrix. [in] rowind[] Array rowind[lrowind] (lrowind >= nnz) Row indices of input matrix. [in] base 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. [in] maxnnz2 Size of arrays val2[] and rowind2[] (must be greater than the number of nonzero elements of output matrix). (maxnnz2 > 0) [out] val2[] Array val2[lval2] (lval2 >= maxnnz2) Values of nonzero elements of output matrix. [out] colptr2[] Array colptr2[lcolptr2] (lcolptr2 >= n + 1) Column pointers of output matrix. [out] rowind2[] Array rowind2[lrowind2] (lrowind2 >= maxnnz2) Row indices of output matrix. [in] base2 Indexing of colptr2[] and rowind2[]. = 0: Zero-based (C style) indexing: Starting index is 0. = 1: One-based (Fortran style) indexing: Starting index is 1. [out] info = 0: Successful exit. = i < 0: The (-i)-th argument is invalid. = j > 0: j elements in input matrix were ignored.
