一个PCA的Matlab程序实例，应用于多维参数的自动降维和分类(The Matlab program example of a PCA applied to the automatic multi-dimensional parameter dimension reduction and classification)

我用的实现图像分水岭分割的代码！感觉还可以，要用的自己拿去改改(I use the watershed segmentation of image code!)

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)

一个50行的Matlab有限元程序（二维传热问题），执行fem2d.m即可。(A 50-line Matlab finite element program (two-dimensional heat transfer problem), the Executive fem2d.m can.)

对数据进行处理,用于小车探测轨迹,自行运行(Data processing)

说明：  这是一个用matlAB计算小球以一定角度和初速度抛出运动的距离的程序(This is a small ball with a matlAB calculated to throw a certain angle and speed of movement from the beginning of the procedure)

papr to differenrt number of subcarrier: we put N = 256,512,1024 and show the output ofp ccdf with papr when we use QPSK modulation. The PAPR ratio is a measure of the dynamic range in OFDM signals. Thus high PAPR induces a high dynamic range which describes high variability in the signal range. complex data sequences are input to the IDFT of an OFDM transmitter then at the output of the IDFT, real and imaginary parts are obtained.
