matlab的toimage程序，虚部转换程序。供大家参考。用于hht中。(matlab' s toimage procedures, the imaginary part of the conversion process. For your reference. For hht in.)

This matlab code uses for recognition the characters

将检测数据常用的.lvm格式读取到workspace的matlab程序(Load lvm files)

针对正弦信号的PID响应进行控制，系统采用基于S函数的simlink仿真。(In view of the sine signal response to the PID control, the system adopts simlink simulation based on S function.)

lssvm程序，采用粒子群算法来优化模型参数(lssvm program, to optimize the model parameters using particle swarm)

图像傅里叶变换所得对数频谱以及高通滤波所得图像(The number of Fourier transform images obtained on the income spectrum, and high pass filtering the image)

改进的正则化正交匹配追踪算法代码，对正则化的规则进行了修改(Improved regularized orthogonal matching pursuit algorithm code for regularization rules were modified)

说明：  BP神经网络经典算法 用于故障检测案例 已经使用过 可放心使用(BP neural network classic algorithm used in fault detection cases It has been used and can be used safely)

matlab 自适应遗传算法源程序，用到了G-S正交化分解，大家可以用QR分解做一下，应该会使程序更简单一点．(Matlab adaptive genetic algorithm source code, used in the G-S orthogonal decomposition. We can do something QR decomposition, the process would be simpler 1:00.)

matlab编写的滤波程序，里面包含了滤波前的信号和滤波后的信号。(matlab prepared by the filtering process, which includes pre-filtering the signal and filtered signal.)
