matlab 数值算法输出格式说明 按照自己的需要输出matlab数据(matlab numerical algorithm output format in accordance with their own needs matlab output data)

基于1962年Gallager提出的规则LDPC码构造方法实现的生成相应LDPC校验矩阵的相应matlab程序。只需要输入相应的码长，列重，行重即可得到具体的矩阵。(1962 Gallager based on the rules LDPC new method of generating the corresponding LDPC calibration matrix corresponding Matlab procedures. Only need to import the corresponding code length, the series, can be re-specific matrix.)

说明：  matlab下一组随机序列测试的源程序代码(Matlab next random sequence testing of the source code)

在已知两源节点，中继节点发射功率的前提下，怎样选择放大系数能够得到最大的传输速率(In the known two source node, the relay node to transmit power premise, how to choose the amplification factor can be obtained the maximum transmission rate)

说明：  结构有限元，基本梁单元、板单元等，线性计算(structure FEM program)

该文件给出了matlab中libsvm工具箱中函数的参数详细说明(This document gives the description of parameters in libsvm toolbox of matlab in detail)
