根据matlab的bvp4c函数的例子思想方法，求解特征值和特征函数，可以解变积分边界的问题，但是须给一个比较精确的初特征值。此为自编程序，已经标明注释。所附为bvp4c相关例子（此从matlab帮助文件节选）。(use the matlab solver bvp4c to obtain the both eigenvalues and eigenfunctions of BVPs, an exact initial eigenvalue is needed.)

用matlab计算并成图形的电路设计中幅频=相位响应图 ，也可为设计计算带通滤波器的中心频率以及Q值提供参考(Using matlab to calculate and graphics into the circuit design of amplitude and frequency = phase response plans can also be calculated for the design of band-pass filter center frequency and Q value to provide reference)
