离散傅里叶变换的程序，可以画出原图和频谱(Discrete Fourier Transform process)

this is the Z transform matlab code

说明：  用MATLAB仿真KL变换，并与DCT变换进行了比较(KL transform using MATLAB simulation and a comparison with the DCT transform)

matlab代码，用来实现adaboost算法的代码，具体的该算法的实现还需要进行一些细节的修改，确保程序的正确运行。(matlab achieve adaboost funtion)

基于ip/iq变换的电力系统APF仿真，用于验证控制算法的性能和进行参数选取的辨识(Power system simulation of APF based on IP/IQ transform, is used to verify the performance of the control algorithm and parameters selection of identification)

计算电路矢量值，本代码主要计算电路的电流傅里叶矢量，稍加修改就可以用于求电路的电源傅里叶矢量(compute circuit vector)

（1）对选定二阶电路图进行仿真，得到仿真的输入、输出数据； （2）建立二阶系统函数，用模拟的方法求解其响应，并用matlab平台求出响应波形； （3）对数据进行拟合； （4）对拟合的结果进行误差分析 ((1) on the selected second order circuit diagram of the simulation to obtain a simulation of the input and output data (2) the establishment of the second order system function, solving the response by the simulation method, and was determined using matlab platform response waveform data (3) be fitted (4) the results of the fitting error analysis)

《matlab编程百例》光盘代码31-35("Matlab programming hundred cases" CD-ROM code 31-35)

说明：  实际系统辨识高增益一阶系统的PID型模糊控制，可是小论文的资料！欢迎交流！(Identification of the actual system of high-gain first-order system PID fuzzy control, but little information on the paper! Welcome to exchange!)

说明：  滤波器设计的目的是对信号进行数据序列的频率变换，去掉其中我们不需要的频率成分，用数字滤波器课实现语音信号去噪(Filter is designed to sequence the signal frequency of the data transformation, which we do not need to remove frequency components, with digital filter class voice signal denoising)
