Purpose:

    Verifies and prints a row or column-oriented sparse matrix.

Returns:

    UMFPACK_OK if Control [UMFPACK_PRL] <= 2 (the input is not checked).

    Otherwise (where n is n_col for the column form and n_row for row
    and let ni be n_row for the column form and n_col for row):

    UMFPACK_OK if the matrix is valid.

    UMFPACK_ERROR_n_nonpositive if n_row <= 0 or n_col <= 0.
    UMFPACK_ERROR_argument_missing if Ap and/or Ai are missing.
    UMFPACK_ERROR_invalid_matrix if Ap [n] < 0, if Ap [0] is not zero,
        if Ap [j+1] < Ap [j] for any j in the range 0 to n-1,
        if any row index in Ai is not in the range 0 to ni-1, or
        if the row indices in any column are not in
        ascending order, or contain duplicates.
    UMFPACK_ERROR_out_of_memory if out of memory.

Arguments:

    Int n_row ;         Input argument, not modified.
    Int n_col ;         Input argument, not modified.

        A is an n_row-by-n_row matrix.  Restriction: n_row > 0 and n_col > 0.

    Int Ap [n+1] ;      Input argument, not modified.

        n is n_row for a row-form matrix, and n_col for a column-form matrix.

        Ap is an integer array of size n+1.  If col_form is true (nonzero),
        then on input, it holds the "pointers" for the column form of the
        sparse matrix A.  The row indices of column j of the matrix A are held
        in Ai [(Ap [j]) ... (Ap [j+1]-1)].  Otherwise, Ap holds the
        row pointers, and the column indices of row j of the matrix are held
        in Ai [(Ap [j]) ... (Ap [j+1]-1)].

        The first entry, Ap [0], must be zero, and Ap [j] <= Ap [j+1] must hold
        for all j in the range 0 to n-1.  The value nz = Ap [n] is thus the
        total number of entries in the pattern of the matrix A.

    Int Ai [nz] ;       Input argument, not modified, of size nz = Ap [n].

        If col_form is true (nonzero), then the nonzero pattern (row indices)
        for column j is stored in Ai [(Ap [j]) ... (Ap [j+1]-1)].  Row indices
        must be in the range 0 to n_row-1 (the matrix is 0-based).

        Otherwise, the nonzero pattern (column indices) for row j is stored in
        Ai [(Ap [j]) ... (Ap [j+1]-1)]. Column indices must be in the range 0
        to n_col-1 (the matrix is 0-based).

    double Ax [nz] ;    Input argument, not modified, of size nz = Ap [n].

        The numerical values of the sparse matrix A.

        If col_form is true (nonzero), then the nonzero pattern (row indices)
        for column j is stored in Ai [(Ap [j]) ... (Ap [j+1]-1)], and the
        corresponding (real) numerical values are stored in
        Ax [(Ap [j]) ... (Ap [j+1]-1)].  The imaginary parts are stored in
        Az [(Ap [j]) ... (Ap [j+1]-1)], for the complex versions.

        Otherwise, the nonzero pattern (column indices) for row j
        is stored in Ai [(Ap [j]) ... (Ap [j+1]-1)], and the corresponding
        (real) numerical values are stored in Ax [(Ap [j]) ... (Ap [j+1]-1)].
        The imaginary parts are stored in Az [(Ap [j]) ... (Ap [j+1]-1)],
        for the complex versions.

        No numerical values are printed if Ax or Az are (double *) NULL.

    double Az [nz] ;    Input argument, not modified, for complex versions.

        The imaginary values of the sparse matrix A.   See the description
        of Ax, above.  No numerical values are printed if Az is NULL. 

        Future complex version:  if Ax is present and Az is NULL, then both real
        and imaginary parts will be contained in Ax[0..2*nz-1], with Ax[2*k]
        and Ax[2*k+1] being the real and imaginary part of the kth entry.

    Int col_form ;      Input argument, not modified.

        The matrix is in row-oriented form if form is col_form is false (0).
        Otherwise, the matrix is in column-oriented form.

    double Control [UMFPACK_CONTROL] ;  Input argument, not modified.

        If a (double *) NULL pointer is passed, then the default control
        settings are used.  Otherwise, the settings are determined from the
        Control array.  See umfpack_*_defaults on how to fill the Control
        array with the default settings.  If Control contains NaN's, the
        defaults are used.  The following Control parameters are used:

        Control [UMFPACK_PRL]:  printing level.

            2 or less: no output.  returns silently without checking anything.
            3: fully check input, and print a short summary of its status
            4: as 3, but print first few entries of the input
            5: as 3, but print all of the input
            Default: 1
