L-M,BP网络算法，用matlab语言编译(LM, BP network algorithm with matlab compiler)

说明：  精通matlab综合辅导与指南，详细介绍了Matlab的操作与编程。(proficient Matlab comprehensive counseling and guidance, details of the operation and Matlab programming.)

moving average filter using widey as low filter in matlab

LDPC bpsk encode decode

很好很强大,是关于双极性基带数据信号对载波进行角度调制产生BPSK信号的，有用的就下取用(strong，just for student who need it.)

It includes coding for walsh code encoding in matlab.The Walsh functions can be generated (or computed) by many methods. We can construct the Walsh functions by: • Using Hadamard matrices • Exploiting the symmetry properties of Walsh functions themselves. • The Hadamard matrix is a square array of plus and minus ones, {+1, -1}, whose rows and columns are mutually orthogonal

偏微分方程的MATLAB解法。 偏微分方程工具箱提供了研究和求解空间二维微分方程问题的一个强大而又灵活实用的环境。(MATLAB Solution partial differential equations. Provided in the toolbox of partial differential equations and differential equations to solve the problem two-dimensional space of a strong and flexible and practical environment.)

EasyMod is a MatLab/Scilab toolbox for teaching modal analysis. It provides a set of functions allowing to establish the identification of modal parameters and these validation. Nowadays, circle-fit, line-fit and least square complex exponential methods are implemented. In addition, some relevant functions are offered in order to complete a modal analysis: operations on the frequency response function (FRF) , generation of FRF from mass, damping and stiffness matrices, MAC (modal assurance criterion) and modal collinearity

超声波声场模拟，可自行设定频率、发射波形、带宽等等，设定换能器矩阵(Ultrasonic sound field simulation, can set the frequency of the transmitted waveform, bandwidth, etc., setting the transducer array)
