这是一个基于QDHE那篇论文编写的一个QDHE代码(This is based on that paper prepared QDHE a QDHE code)

支持向量机回归模型，可应用于经济、金融时间序列预测！(SVM Model)

The subroutines glkern.f and lokern.f use an efficient and fast algorithm for automatically adaptive nonparametric regression estimation with a kernel method. Roughly speaking, the method performs a local averaging of the observations when estimating the regression function. Analogously, one can estimate derivatives of small order of the regression function.

fft示範,取前10 waves,X-Hz,Y-phase angle(fft demonstrations, for the first 10 waves, X-Hz, Y-phase angle)

this code correct bias field of MR images

生成正弦波，不需要调用sin函数，利用的查表法(Generate a sine wave, you do not need to call the sin function using table look-up method)

LDPC码在MATLAB中的八环成功仿真算法，大围长QC-LDPC码。值得学习一下(LDPC code in MATLAB in the eight-ring successful simulation algorithm, large-scale long QC-LDPC code. Worth learning)

说明：  matlab算法练习，包括牛顿迭代法，赛德尔迭代法等(matlab learning)

程序实现了生成决策树并使用决策树对离散特征向量进行分类。在判断是否要继续生成叶节点时采用entropy来作为impurity的measurement.(Program and use the decision tree decision tree to generate discrete feature vectors for classification. In determining whether to continue generating leaf nodes using entropy as the impurity of the measurement.)
