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...

python中的 sympy库是一款符号运算库,功能强大。这里测试其求微分方程的功能。The sympy library in python is a symbolic operation library with powerful functions. Here we test its function of finding differential equations. 我们可以试试用sumpy求解单自由度粘滞阻尼体系自由振动的运动方程。We can try to ...
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...
DifferentialEquations.jl This is a suite for numerically solving differential equations written in Julia and available for use in Julia, Python, and R. The purpose of this package is to supply efficient Julia implementations of solvers for various differential equations. Equations within the realm of...
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...
