z_csx_check_sym() void z_csx_check_sym ( int  n, const doublecomplex  val[], const int  ptr[], const int  ind[], int *  info  ) Check symmetry of sparse matrix (Complex matrices) (CSC/CSR) Purpose This routine checks the symmetry of sparse matrix in CSC or CSR format. Parameters [in] n Number of rows and columns of the 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] ptr[] Array ptr[lptr] (lptr >= m + 1) Column pointers (if CSC) or row pointers (if CSR) of input matrix. [in] ind[] Array ind[lind] (lind >= nnz) (nnz is the number of nonzero elements of input matrix) Row indices (if CSC) or column indices (if CSR) of input matrix. [out] info = i < 0: The (-i)-th argument is invalid. = 0: Input matrix is not symmetric/Hermitian matrix. = 1: Input matrix is symmetric matrix. = 2: Input matrix is Hermitian matrix. = 11: Internal program error (could not create transpose matrix).
