傅里叶变换功能的实现，虽然是非常见得的频率成分，但是还是实现了基本的傅里叶变换功能，并不是matlab自带的fft函数。实现了频谱分析可视化。(Fourier transform function, although it is very frequency components appear, but still achieve the basic function of the Fourier transform, comes not matlab fft function. Achieve a spectral analysis visualization.)

验证在时域AWGN添加的SNR的数值等于在频域获得的SNR数值(Validation added in the time domain SNR value equal to access to the SNR in the frequency domain values)

基本的粒子滤波程序可以修改参数，可以运行(The basic particle filter program can modify the parameters, you can run)

程序实现ofdm系统中通过用选择性映射（SLM）来改善系统的峰均比（PAR）。减少较大功率峰值出现(Program ofdm system by using selective mapping (SLM) to improve the system of PAR (PAR). Reduce peak power greater)

canny边缘算法的实现，代码比较简单，能实现。(canny edge algorithm, the code is relatively simple to achieve.)

带电粒子在非匀强磁场中运动时，画出其轨迹图形(Charged particle moving in an inhomogeneous magnetic field when the draw its trajectory graphics)

迭代学习控制系统仿真及其PID参数整定-华东石油大学本科毕业论文 (Iterative Learning Control System Simulation and PID parameter tuning- East China Petroleum University undergraduate thesis)

The brief idea of the algorithm is that every image s pixel is set to black if its brightness is T percent lower than the average brightness of the surrounding pixels in the window of the specified size

在对图像进行处理时需要计算图像的分维数，此函数就是用来计算图像的分型维数(In the process of image processing, it is needed to calculate the fractal dimension of the image, which is used to calculate the fractal dimension of the image)

声波方程正演,时间域，加吸收边界条件，可以自己编辑模型(Acoustic wave equation forward, time domain, plus absorbing boundary conditions can edit their own model)
