dense_csc() void dense_csc ( int  m, int  n, int  lda, const double  a[], int  maxnnz, double  val[], int  colptr[], int  rowind[], int  base, int *  info  ) Dense matrix -> CSC Purpose This routine converts the dense matrix to the sparse matrix in CSC format. 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] lda Leading dimension of array a[][]. (lda >= m) [in] a[][] Array a[la][lda] (la >= n) Input matrix. [in] maxnnz Size of arrays val[] and rowind[] (must be greater than the number of nonzero elements of the input matrix). (maxnnz > 0) [out] val[] Array val[lval] (lval >= maxnnz) Values of nonzero elements of output matrix in CSC format. [out] colptr[] Array colptr[lcolptr] (lcolptr >= n + 1) Column pointers of output matrix in CSC format. [out] rowind[] Array rowind[lrowind] (lrowind >= maxnnz) Row indices of output matrix in CSC format. [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. [out] info = 0: Successful exit. = i < 0: The (-i)-th argument is invalid. = 10: Insufficient outout array size (maxnnz is too small).
