引入ECG信号bat等文件，是不可少得的M文件(The introduction of ECG signal bat and other documents is indispensable document obtained M)

Sound synthesis with Matlab. Simple implementation of a multi-oscillator synthesizer. Includes FM modulation, 2 LFO s, 2 Env s. Good to learn the basis of sound synthesis in Matlab.

说明：  Least squares Identification system

signal proccessing and furier transform

matlab对一幅图像，采用半径值为20、80、200的截止频率进行理想低通滤波，观察其结果。要求给出原图像及相应的付利叶频谱图和滤波结果(For an image, using the radius value of the cutoff frequency 20,80,200 ideal low-pass filter to observe the results. Required to give the original image and the corresponding Fourier spectrum and filtering results)

基于高斯混合模型和EM（Expectation Maximization）算法的SAR影像变化监测算法，并附带示例。总体思路是首先将两个时期的SAR影像做log和ratio运算，生成差分影像，然后通过EM算法估计高斯混合模型的参数，最后根据高斯混合模型最大概率，生成变化监测结果。(Unsupervised change detection method for SAR images using EM algorithms of Gaussian mixture model)

这是一个带有磁链观测器的永磁同步电机矢量控制仿真模型。(This is a permanent magnet synchronous motor vector control simulation model with flux observer.)

PcA和Fisher方法的人脸识别,希望对大家有用，(PcA Fisher and methods of face recognition, we hope to useful,)

修正的canny算子进行边缘检测提取，具有高的检测率，精确的定位，明确的相应。(Modified canny operator to extract edge detection with high detection rate, accurate positioning and clear accordingly.)

this is genaral techniques involves in noise cancellation and this matlab version
