计算涡旋相位，matlab画不同拓扑电荷的涡旋光束(The vortex phase is calculated and MATLAB is used to draw vortex beams with different topological charges)

this code is knows Mean Shift algorithm

开关电源 PWM PFM仿真 SIMULINK(Switching power supply PWM PFM simulation SIMULINK)

Lozi混沌映射的线性反馈控制，给出了一般形式下的Lozi系统的混沌运动被控制到不动点的参数范围.并对Lozi映射的1个混沌吸引子进行了有效控制 (Lozi map chaotic linear feedback control, gives the general form of the Lozi system to be controlled chaos of the parameters of the fixed point range and Lozi map of a chaotic attractor for the effective control)

利用matlab实现数字全息显微镜再现程序，可用来参考(Digital holographic microscopy using matlab reproduction program can be used to reference)

sharppart function for wavelet analysis

说明：  自己做的一个Matlab小时钟，可以自己更换背景图片，供大家互相学习(This is a samll clock based matlab,you can change the background by yourself.Hope your enjoy about it!)

说明：  双稳系统随机共振仿真与实例，用于弱信号的检测(Bistable stochastic resonance simulation instance, for the detection of weak signals)

简单SENSE图像重建，即使通过反傅里叶变换重建出最终图像(The data was acquired from 4-channel array coil using EPI sequence (2-shot, matrix: 64X64, TE: 50 ms) at a 1.5T scanner. The code estimates the coil sensitivity profiles directly from the image with anatomical contrast by low-pass smoothing. Subsequently, k-space data were decimated to simulate 2.0-fold acceleration (R=2.0). Finally, using least-squares estimate, the reconstructed full-FOV spin density image is obtained)

very good simulation for multipath channel
