Solve a system of ordinary differential equations using lsoda from the FORTRAN library odepack. Solves the initial value problem for stiff or non-stiff systems of first order ode-s: dy/dt = func(y, t, ...) [or func(t, y, ...)] where y can be a vector. 在scipy1.1.0版本中odeint...
The g2 contains gamma2 by definition # one could define these equations the other way, but I prefer this form result = sm.solve([gamma2-g2,beta2-b2,xg2-x2,yg2-y2], # this line tells the solver what variables we want to solve to [gamma2,beta2,xg2,yg2] ) # print the result...
method:字符串或OdeSolver,可选 使用的积分方法: ‘RK45’ (default): Explicit Runge-Kutta method of order 5(4)[1]. The error is controlled assuming accuracy of the fourth-order method, but steps are taken using the fifth-order accurate formula (local extrapolation is done). A quartic interpo...

The DifferentialEquations.jl SDE Tutorial explains how the matrix form of the diffusion term corresponds to the summation style of multiple Wiener processes. Essentially, the row corresponds to which system the term is applied to, and the column is which noise term. So du[i,j] is the amount...
