direct calculation of fft

全相位FFT的matlab程序，结果很好，相位检测精度很高(all phase fft program in matlab, the out is good)

matlab仿真模型，可以当作毕业设计内容使用。(matlab simulation model can be used as a graduation project content.)

基于IFFTFFT的OFDM系统仿真。完整的可运行的代码。信源用randn产生，信道为高斯白噪声，如用其他，可以方便自行修改。(Based on IFFT FFT of OFDM system simulation. Complete code can be run. Generated using randn source, channel for the Gaussian white noise, such as the use of other, you can easily modify.)

透视变换,由于摄像头存在透视效果 所以很多时候需要进行世界坐标系和图像坐标系下的转换(perspective transformation, As the camera lens effect so there is often the need for the world coordinate system and the image coordinate system conversion)

very useful book for IGBT designers

分数阶PID比一般PID多了2个可调参数，实现了常规PID所无法实现的控制功能，并且更精确有效(Fractional PID PID more than two adjustable parameters, and can not be achieved by the conventional PID control functions, and more accurate and efficient)

Small speech recognition program demo

在matlab环境中自动识别连通区域的大小,从先验概率中采样，计算权重，小波包分析提取振动信号中的特征频率。( Automatic identification in the matlab environment the size of the connected area, Sampling a priori probability, calculate the weight, Wavelet packet analysis to extract vibration signal characteristic frequency.)

1 swing bus、1 PQ bus、2 transfermor 以matlab劃出結構圖後計算各線路的電流電壓(1 swing bus, 1 PQ bus, 2 transfermor matlab draw diagram after calculation of current and voltage of each line)
