利用已知的四阶R-K方法求解高阶常微分方程(Using the known four order R-K method to solve high order ordinary differential equation )

有限插分法求取泊松方程，非常经典啊，欢迎下载(Finite Difference Method to strike a Poisson equation, very classic ah, welcome to download)

This program is designed to find the parameters of the method of least squares, building eksperimetalnyh and theoretical curves for to assess the quality of approximation for propagation occurs trend of all their characteristics: propagation time, phase, amplitude and polarization. On the smooth running pa - ters inevitably superimposed random fluctuations. For devices they associated with the noise of radio circuits, to propagate in the Natural governmental environments, radio waves to the presence of turbulent fluctuations. Code is of interest mainly to radiophysicists(This program is designed to find the parameters of the method of least squares, building eksperimetalnyh and theoretical curves for to assess the quality of approximation for propagation occurs trend of all their characteristics: propagation time, phase, amplitude and polarization.
