/* CHOLMOD Check module.
 *
 * Routines that check and print the 5 basic data types in CHOLMOD, and 3 kinds
 * of integer vectors (subset, perm, and parent), and read in matrices from a
 * file:
 *
 * cholmod_check_common	    check/print the Common object
 * cholmod_print_common
 *
 * cholmod_check_sparse	    check/print a sparse matrix in column-oriented form
 * cholmod_print_sparse
 *
 * cholmod_check_dense	    check/print a dense matrix
 * cholmod_print_dense
 *
 * cholmod_check_factor	    check/print a Cholesky factorization
 * cholmod_print_factor
 *
 * cholmod_check_triplet    check/print a sparse matrix in triplet form
 * cholmod_print_triplet
 *
 * cholmod_check_subset	    check/print a subset (integer vector in given range)
 * cholmod_print_subset
 *
 * cholmod_check_perm	    check/print a permutation (an integer vector)
 * cholmod_print_perm
 *
 * cholmod_check_parent	    check/print an elimination tree (an integer vector)
 * cholmod_print_parent
 *
 * cholmod_read_triplet	    read a matrix in triplet form (any Matrix Market
 *			    "coordinate" format, or a generic triplet format).
 *
 * cholmod_read_sparse	    read a matrix in sparse form (same file format as
 *			    cholmod_read_triplet).
 *
 * cholmod_read_dense	    read a dense matrix (any Matrix Market "array"
 *			    format, or a generic dense format).
 *
 * cholmod_write_sparse	    write a sparse matrix to a Matrix Market file.
 *
 * cholmod_write_dense	    write a dense matrix to a Matrix Market file.
 *
 * cholmod_print_common and cholmod_check_common are the only two routines that
 * you may call after calling cholmod_finish.
 *
 * Requires the Core module.  Not required by any CHOLMOD module, except when
 * debugging is enabled (in which case all modules require the Check module).
 *
 * See cholmod_read.c for a description of the file formats supported by the
 * cholmod_read_* routines.
