rung-kutta 4 he inputs func, x0 and y0 define an IVP y = func(x,y), y(x0) = y0. This provides an approximation to y(x0:h:xn) using fourth-order Runge-Kutta method with step size h-rung-kutta 4 he inputs func, x0 and y0 define an IVP y = func

经典Lorenz方程组蝴蝶效应的计算模拟程序，帮助更好了解非线性科学，源代码小巧有效，使用四阶龙格-库塔算法，生成.txt文件，之后自行导入画图软件作3D图即可得到蝴蝶效应图-Classical Lorenz equations to calculate the butterfly effect simulation program, to help better understand the nonlinear science, source code compact and effectiv

GPL this is a code for the driven harmonic oscillator with Rung-Kutta approach
