FFT

这个程序是matlab的灰度变换程序我也是往上下的(Gray-scale transformation)

感知器分类的一个例子，分成两类的分类器,用MATLAB实现(perceptron example for matlab)

segmenting image processing using lazy snaping

gray scale coding method

说明：  利用自适应粒子群进行寻优，实验效果良好，其中具体参数要根据实际调节(Using adaptive particle swarm optimization, the experimental results are good, and the specific parameters should be adjusted according to the actual situation.)

说明：  在MATLAB环境下的3780点FFT仿真(The Simulation of 3780 point FFT in MATLAB environment.)

线性调频脉冲信号的产生，以及线性调频脉冲的dechirp处理(Chirp signal generation, and the chirp of dechirp processing)

it is useful and helpful for my research work

主成分分析代码，用matlab实现的，请大家参阅。(Principal component analysis code, matlab implementation, please refer to the.)

选用DB小波对故障电力信号进行分解，从图中可轻易判断出故障点。(DB wavelet used to decompose the fault signal power, from the figure can easily determine the point of failure. )
