diffeqpy is a package for solving differential equations in Python. It utilizes DifferentialEquations.jl for its core routines to give high performance solving of many different types of differential equations, including:Discrete equations (function maps, discrete stochastic (Gillespie/Markov) simulations...
下面给出一个python示例: 首先,安装torchdiffeq库: pip install torchdiffeq 以下代码定义并训练一个简单的神经ODE模型: import torch import torch.nn as nn from torchdiffeq import odeint class ODEFunc(nn.Module): def __init__(self): super(ODEFunc, self).__init__() self.net = nn.Sequential...

新版本+新语法, DifferentialEquations是可以通过的。我这次仍报错在Plots绘图上。 顺便弄懂了“p”为要传递的参数,改用PyPlot绘图,成功: using DifferentialEquations f(u,p,t) = 1.01*u u0 = 1/2 tspan = (0.0,1.0) prob = ODEProblem(f,u0,tspan) sol = solve(prob, Tsit5(), reltol=1e-8, abs...

Partial differential equations (PDEs) are ubiquitous to the mathematical description of physical phenomena. Typical examples describe the evolution of a field in time as a function of its value in space, such as in wave propagation or heat flow. Many existing PDE solver packages focus on the imp...

i have tried to break this down into 2 single order equations as d_theta/dt = A; dA/dt = -(c/m)*A - (g/l)*sin_theta; after seeing all the solved examples, i cant figure out what i am going to with sin_theta in eq2 is theta substituted as A*t from eq1?? and how am ...
