z_dense_coo() void z_dense_coo ( int  m, int  n, int  lda, const doublecomplex  a[], int *  nnz, doublecomplex  val[], int  rowind[], int  colind[], int  base, int *  info  ) Dense matrix -> COO (Complex matrices) Purpose This routine converts the dense matrix to the sparse matrix in COO 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,out] nnz [in] Size of arrays val[] and rowind[] (must be greater than the number of nonzero elements of the input matrix). (nnz > 0) [out] The actual number of nonzero elements of the input matrix. [out] val[] Array val[lval] (lval >= maxnnz) Values of nonzero elements of output matrix. [out] rowind[] Array rowind[lrowind] (lrowind >= maxnnz) Row indices of output matrix. [out] colind[] Array colind[lcolind] (lcolind >= maxnnz) Column indices of output matrix. [in] base Indexing of rowind[] and colind[]. = 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).
