曲面样条插值实现（没用householder变换，不稳定）(Surface Spline Interpolation (useless householder transformation, instability))

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.)
