z_dense_nnz() void z_dense_nnz ( int  m, int  n, int  lda, const doublecomplex  a[], int *  nnz, int *  info  ) Number of nonzero elements in dense matrix (Complex matrices) Purpose This routine counts the number of nonzero elements in dense matrix. Parameters [in] m Number of rows of the matrix. (m >= 0) [in] n Number of columns of the matrix. (n >= 0) [in] lda Leading dimension of array a[][]. (lda >= m) [in] a[][] Array a[la][lda] (la >= n) The dense matrix. [out] nnz Number of nonzero elements in the matrix. [out] info = 0: Successful exit. = i < 0: The (-i)-th argument is invalid.
