龙格---库塔方法是求解微分方程比较常用的方法,在理解数学上是怎么一回事后,编制这个程是相当容易的,就是个迭代的过程.步长的选取也是很有讲究的,过小的步长反而会导致误差累积过大.
相关的理论请参考相关的数值算法的书籍，我这里只给出关键的函数及主程序段，其余相关的细节就不再一一罗列了.-Runge - Kutta method to solve the differential equation is more commonly used method, in understanding how mathematics is one thing, the availability of the way is easy, it is an iterative process. the selection step is meticulously planned, a small step but will result in cumulative error too large. the theory refer to the numerical algorithm books, here I am only given the key function and main program, and the rest of the details will no longer be listed on January 1.
