wigner-and-chafen

代码说明：

  第一部分是关于wigner-ville程序的三个源函数（wigner分布、伪wigner分布、平滑伪wigner分布）；第二部分是关于差分的一阶、二阶导数的子函数、源函数及表达仿真实例，这两部分都是matlab环境下源程序。(The first part is a function of three sources wigner-ville program (wigner distribution, pseudo wigner distribution, smoothed pseudo wigner distribution) the second part is about the first difference, the second derivative of the subroutine, the source function and expression simulation examples These two parts are the source matlab environment.)
