行列式比有色噪声matlab实现通过构造H矩阵计算得到DR，通过对DR的观察得到结果。(Determinant than the realization of colored noise matlab calculated by constructing a matrix H DR, DR, observed by the results.)

利用保留交叉验证(hold-out)的特征选择，有筛选排序的功能，并最终可以输出对应特征下标。(The use of cross-validation reserved (hold-out) feature selection, there is sort of filtering function, and eventually you can output the corresponding feature subscript.)

对于大量照片求取通道内气泡长度和频率生成信息，每张都求取，计算速度较慢(For a lot of photos to strike a channel length and frequency of the bubble generation information, each have to strike, the calculation speed is slow)

一本微分方程数值分析教材,pdf,希望对大家编程能有所帮助A.first.course.in.the.numerical.analysis.of.differential.equations,.Iserles,.2ed,.CUP,.2009(Numerical analysis of a differential equation textbook, pdf, we want to programming can help A.first.course.in.the.numerical.analysis.of.differential.equations, .Iserles, .2ed, .CUP, .2009)

IS-95系统的仿真，仿真原理对应《通信系统仿真》第二版的12章的最后一个例子(simulation of IS-95 system, and the thoery of this code if from a book named simulation of communication systems . If you want to have a deep uderstanding on the code, please refer to chaper 12, the last example)
