deconvolution

说明：  基于R/T系数法求解计算瑞利波波速，算法被改进过的，速度很快(Based on R/T coefficient method calculation of the Rayleigh wave speed, the algorithm had been improved, very fast)

该程序描述了系统传递函数、空间状态方程以及微分方程相互之间的转换。(The program describes the system transfer function, state space equations and differential equations between the conversion.)

好几种贝塞尔函数的解法，非常经典的，有需要请下(Bessel function of several of the Solution, very classic, there is a need to call on the next)
