这是一个把神经网络直接应用于轴承的故障诊断的程序，输入轴承的信号，直接得答案(This is a direct application of neural network in bearing fault diagnosis procedures, input bearing signal, a direct answer)

fft相关法估计chirp信号调频率，一种高效的线性调频信号参数估计方法(A highly efficient linear FM signal parameters estimation method )

I wrote this program for coloring any map with only 4 colors. Input for it is an bitmap file with 24 bit colors (must gray/scale). Output is a bitmap which is colored with maximum 4 colors.

说明：  基于DWT的图像压缩，上数字图像处理可的大作业(DWT Compression)

基于无传感器的矢量控制的matlab的程序框图，经试验，可以正常运转(Based sensorless vector control matlab block diagram, the test can be normal operation)

该代码采用matlab和C混合编写，是采用随机梯度的方法训练线性分类器，它可用于数据、图像等的多类分类情况。参考论文：Good Practice in Large-Scale Learning for Image Classification(This a Stochastic Gradient Descent algorithm used to train linear multiclass classifiers. It is biased towards large classification problems (many classes, many examples, high dimensional data).)

频域波束成形算法，适用于所有一维和二维阵列的波束成形计算。对于采样时间较短的信号，采用了2次分段，对于采样时间足够的信号则只需要1次分段计算。计算结果包含成像图结果和各扫描点处的频谱结果(Frequency domain beamforming algorithm, applicable to all one-dimensional and two-dimensional array beam forming calculations. For shorter sampling signal, using a second segment, the sampling time sufficient signal need only 1 segment calculations. Calculation results include the results of spectral imaging of the results of each scan point)

代码工具箱distmesh的示例代码，里面例子很全注释很详细(Code toolbox distmesh sample code, the example of the full annotation is very detailed)
