Matlab实现的全相位频谱分析，可以自行设定点数和输入序列。结果包括频谱图和与普通fft的对比(Matlab to achieve all-phase spectral analysis, can draw up a point and input sequence. The results include the spectral figure and the comparison with ordinary fft)

this program finds the number of zero crossings in a given signal.

求解数独的小程序 其中采用了图形界面，对初学者可以参考图形界面的编写方法。 求解数独算法比较简单，但是其中注释很少 (A small program to solve Sudoku Which uses a graphical interface, a graphical interface for beginners can refer to the preparation method. Sudoku solving algorithm is relatively simple, but very few comments which)

快速中值滤波，在大数据量的情况下速度很快，论文“Median Filter in Constant Time”的C语言实现(C souce code for "Median Filter in Constant Time")

混响器设计 能够实现对音频不同风格的设置，功能使用。(Reverb is designed to achieve different styles of audio settings, feature use.)

EM 算法是求参数极大似然估计的一种方法，它可以从非完整数据集中对参数进行估计，是一种非常简单实用的学习算法。这种方法可以广泛地应用于处理缺损数据、截尾数据以及带有噪声等所谓的不完全数据，可以具体来说，我们可以利用EM算法来填充样本中的缺失数据、发现隐藏变量的值、估计HMM中的参数、估计有限混合分布中的参数以及可以进行无监督聚类等等。(Expectation Maximization image segmentation Input: ima: grey color image k: Number of classes Output: mask: clasification image mask mu: vector of class means v: vector of class variances p: vector of class proportions )

This is about doppler normalization for satelit communication simulation with 2.4 Ghz freq. You can change the frequency for know about doppler efek maxsimum and minimum.
