var模型的实现。针对var模型的算法，估计模型的参数。并对其进行检验(achieve var model. Var model for the algorithm, the estimated parameters of the model. And its test)

读取和写入raw格式图像，此格式图像文件存储一幅图中的全部像素点，并以每个像素点16bit数据保存(read and write a raw format 16-bit image)

MFCC参数和LPCC参数需要频繁使用的语音的说话人识别分析还需要使用大量的这些特征参数,这就需要研究MFCC和LPCC算法和参数提取的原则。因为我们需要了解与人交谈的过程中,我们要进行建模 率不构成线性关系，而更偏向于对数关系，这就使得人耳对低频信号比高频信号更敏感。Mel频率的提出是为了方便人耳对不同频率语音的感知特性的研究。频率与Mel频率的转换公式为(MFCC parameters and LPCC parameters are parameters of speaker recognition which requires frequent use of voice analysis also need to use a lot of these characteristic parameters, This requires research MFCC and LPCC algorithm and the principle of parameter extraction. Because we need to understand the process of talking to people, we want to conduct a speaker modeling the perception of the human ear does not constitute a linear relationship with frequency, and prefer to logarithmic relationship, which makes the human ear is sensitive to low frequency signal is better than high frequency signal. Mel frequency is put forward in order to facilitate the ear of the study of speech perception characteristics of different frequency. For frequency and Mel frequency conversion formula)

这是功率谱估计MVDR算法的实现，代码能仿真成功(This is the power spectrum estimation in MVDR algorithm, the code can be successful simulation)

WGS-84 -> ECEF ECEF -> WGS-84 极坐标系 -> ECEF ECEF -> 极坐标系(WGS-84-> ECEF ECEF-> WGS-84 polar-> ECEF ECEF-> polar)

一道关于卫星导轨的数学建模代码；本人自己数学建模赛的源代码，共参加数学建模参考(A guide rail on the mathematical modeling of satellite code)

说明：  此算法为基于最大似然方法的DOA估计 是区别于子空间类的DOA算法 但需要多维搜索 计算量较大(This algorithm is based on the maximum likelihood method of DOA estimation is different from the sub-space kind of DOA algorithm but calculating the volume of the larger multi-dimensional search)

说明：  G.729编码，解码的程序实现。支持多种语音格式。(G.729 encoding and decoding process realization. Support multiple audio format.)
