The main features of the considered identification problem are that there is no an a priori separation of the variables into inputs and outputs and the approximation criterion, called misfit, does not depend on the model representation. The misfit is defined as the minimum of the l2-norm between the ...

技术资料 耦合长短波方程的多辛方法

本论文主要是研究耦合长短波方程的多辛算法,耦合的长短波方程是Schrodinger-Kdv方程组的特殊形式,本文构造了 Euler-box格式、多辛 Preis sman洛式和 Fourier拟谱格式求解耦合长短波方程。然后与已知的 Crank Nicolson方法和时间分裂步方法比较。并得出 Euler box格式是半显式的,空间方向一阶精度时问方向一阶精度的数值 ...
