Lamb波的频散曲线是进行超声Lamb波无损检测的重要依据。本程序对Rayleigh2Lamb方程进行了分析,给出了板中Lamb波频散曲线的数值计算方法,通过Matlab软件对求解过程进行编程,绘制出Lamb波在铝板中传播的相速度和群速度曲线,对推广应用Lamb波进行无损检测具有实际意义。(dispersion curve of lamb)

离散系统Z域分析 实验步骤： 主界面下进入实验六的“离散系统Z域分析”，输入分子多项式的系数向量 按照 z 降幂的顺序输入，如：，输入为。 输入分母多项式的系数向量，按照 z 降幂的顺序输入。 鼠标单击确定按钮，显示系统函数的幅频特性曲线，相频特性曲线。(Z-domain analysis of discrete-time systems experimental steps: the main interface into the six experiments the " Z-domain analysis of discrete-time systems" , enter the coefficient of polynomial vector elements z in accordance with the descending order of power input, such as:, input. Denominator polynomial coefficients input vector, z in accordance with the order of descending input power. Mouse click OK button, and display system function curve of amplitude-frequency characteristics, phase-frequency characteristic curve.)

This is a m - file whiuch you can import music files such as wav into matlab by it

numerical methods analysis and the taget for the same

this is for matlab function

支持向量机分类程序，很好用，我已经调试过。(Support vector machine classification procedures, is very good with, I have been testing.)

passion方程的第一类边界条件的数值解，边界条件过于复杂而无法求得解析解。这就需要借助于数值法来求电磁场的数值解。有限差分法便是一种比较容易的数值解法。(Numerical Solution of the first boundary condition passion equations and boundary conditions are too complex to be obtained by analytical solution. This requires the help of numerical methods to find numerical solution of electromagnetic fields. Finite difference method is a relatively easy numerical method.)

运用block-matching法进行去噪处理，matlab源代码。(block match)

分别仿真16阵元的十字阵列、线阵、面阵和圆阵的LS算法的方向图，对阵列信号处理的同学有帮助。(Simulation 16, respectively, the cross element array, linear array, planar array and the circular array pattern LS algorithm, array signal processing to help students.)

说明：  LTE-A中的AF和DF中继研究，比较有用(LTE-A in the AF and DF relaying research, more useful)
