It is not clear what "y1" and "fy1" etc. contain. As long as we cannot see, how the equations are coupled, it is impossible to guess how this can be implemented. The anonymous function for "dx1/dt" has teh input "x1", but does not use it?!
I have to solve a system of ODEs using ODE45 function. Here is the function which describes my equitions. function dNdt = rateEquations(t, y) %populations of corresponding state Ng = y(1); Ns = y(2); Nt = y(3); %All constants used are dropped for the sake of easy rea...
% Solve the System of First-Order ODEs sol = ode45(M,[0 20],[2 0]); % 常见用法: % [ t , y ] = ode45( odefun , tspan , y0 ) % odefun ,用以表示f(t,y)的函数句柄或inline函数i,t是标量,y是标量或向量; % tspan 若是二维向量[t0,tf],表示自变量初值t0和终值tf;若是高维向量[...
the name suggests, solve the model using the same step size from the beginning to the end of the simulation. You can specify the step size or let the solver choose it. Generally, decreasing the step size increases the accuracy of the results and the time required to simulate the system. ...

求解方程:使用MATLAB的solve函数来求解方程。假设方程的系数分别为a、b、c、d,可以使用以下代码求解方程:roots([a, b, c, d])。该函数将返回方程的根。 绘制方程曲线:使用MATLAB的plot函数来绘制方程的曲线。可以使用以下代码绘制方程的曲线:x = linspace(start, end, num_points); y = ax.^3 + bx.^2...
The initial guess of the solution also should satisfy this condition. When you solve a singular BVP, the solver requires that your function odefun(x,y) return only the value of the f(x, y) term in the equation. The term involving S is handled by the solver separately using the '...
