低通滤波器，使用FDATOOL，得到滤波系数，然后使用matlab仿真，可以直接运行，可以查看原始波形和滤波后的波形，稍微修改可以移植到嵌入式编程中，本人项目使用(Low-pass filter, use FDATOOL, get the filter coefficients, and then use the matlab simulation, can be run directly, you can view the original waveform and waveform after filtering, a slight modification can be ported to embedded programming, I project uses)

matlab奇异值分解的范例程序，对数据进行降噪处理。(Singular Value Decomposition matlab sample program for data processing for noise reduction.)
