FastTools，比系统自带的Vlookup sum自带的快多啦！！(FastTools, a lot faster than the Vlookup sum comes with a built-in system!!)

LT编码的东西，不知道好不好 就是上传试试(this is lt)

说明：  对心直动凸轮机构压力角的计算 计算斜齿轮公法线长度及其偏差 优化设计的分析与计算(Direct action on the heart cam pressure angle calculating the length of common normal helical gear calculation and deviation analysis and calculation of optimal design)

QC-LDPC码生成矩阵编程，围长为12，无4环(The program searches for a girth 12 QC-LDPC code given size of sub-matrix, row and column weights. The configuration of sub-matrices could also be changed. The program offers flexibility in constructing girth-12 QC-LDPC codes compared to other algorithms. The program builds a Tanner graph by connecting groups of rows and columns. A connection is made if it does not form less than twelve-cycles. The program may fail to find a code given particular parameters. It also does not find the smallest codes compared to other algorithms. )
