模糊聚类；涉及事物之间的模糊界限时按一定要求对事物进行分类的数学方法。聚类分析是数理统计中的一种多元分析方法，它是用数学方法定量地确定样本的亲疏关系，从而客观地划分类型。事物之间的界限，有些是确切的，有些则是模糊的。例如人群中的面貌相像程度之间的界限是模糊的，天气阴、晴之间的界限也是模糊的。当聚类涉及事物之间的模糊界限时，需运用模糊聚类分析方法。模糊聚类分析广泛应用在气象预报、地质、农业、林业等方面。通常把被聚类的事物称为样本，将被聚类的一组事物称为样本集。模糊聚类分析有两种基本方法：系统聚类法和逐步聚类法。 (Fuzzy clustering )

Flexible construction of girth-six QC-LDPC Codes(The program constructs girth-six QC-LDPC codes given row-weight,k, column-weight,j, and sub-matrix size,m. The obtained parity-check matrix is stored in H. The construction has flexibility in that j,k and m can be varied.The program achieves girth-six by applying the row-column constraint. There are m rows in j submatrices. No two rows should share the same column more than once. This constraint is applied to avoid 4-cycles. The construction has flexibility in that j,k and m can be varied.)
