主要介绍数据拟合的方法，是自己学习后整理出来的程序，欢迎下载！(The method focuses on data fitting, after sorting out their own learning program, welcome to download!)

实现了2FSK调制的一个小程序，为进行通信类学习者提供了一个参考(Implementation of 2FSK modulation of a small program, for beginners communication provides a reference for the study)

波束形成原代码，波束形成的仿真(beam forming the original code, beam forming simulation)

信号预处理程序，包括最小二乘法，滑动平均法，五点三次法以及五点滑动法(Signal preprocessing programs, including least square, sliding average,five point three average and five-point sliding)

ULTRSIM是一款超声图像仿真软件，可以作为超声图像仿真研究的工具，附有matlab代码(ULTRSIM is an ultrasound image simulation software can be used as a tool for simulation of ultrasonic images)

采用罗曼Ⅲ型编码方式且以字母K，利用MATLAB语言制作了一个迂回相位编码的傅立叶变换全息图。(Ⅲ type encoding using Roman letters and with K, the use of MATLAB language created a detour phase encoding of Fourier transform holograms.)
