Function suitesparse_camd_sys::camd_valid

pub unsafe extern "C" fn camd_valid(
    n_rows: SuiteSparseInt, 
    n_cols: SuiteSparseInt, 
    ap: *const SuiteSparseInt, 
    ai: *const SuiteSparseInt
) -> SuiteSparseInt

Checks if the matrix A represented by its index pointer array ap and its indices array ai is suitable to pass to camd_order.

Will return CAMD_OK if the matrix is suitable, and CAMD_OK_BUT_JUMBLED if the matrix has unsorted or duplicate row indices in one or more columns. The matrix must be square, ie n_rows == n_cols.

Otherwise CAMD_INVALID will be returned.
