[t,y] = ode45(odefun,tspan,y0), where tspan = [t0 tf], integrates the system of differential equations y′=f(t,y) from t0 to tf with initial conditions y0. Each row in the solution array y corresponds to a value returned in column vector t. All MATLAB® ODE solvers can solve...
Open in MATLAB Online I have a question for system of ordinary differential equations, because Matlab gives some strange solution as output. There is the code: Jo1=1; Jo2=2; Jo3=3; Mo1=1; Mo2=1; Mo3=1; f=@(t,x)[x(4).*sin(x(3))./sin(x(2))+x(5).*cos(x(3))...

From what I understand, you are trying to solve a system of equations whose solution vector contains contra propagating and copropagating vectors with respect to a length parameter(z). It addresses both problems, boundary value problem and an initial condition ...
Open in MATLAB Online The solution below follows closely the "Solve Nonstiff Equation" example in the ode45 documentation. We first need to write an external function that encodes the differential equations in a single array variable y; let's choose , , , and . The code for solving the...
Matlab使用ode45求解器求解常微分方程 引言 ode的全称是Ordinary differential equations(常微分方程)的缩写。 ode45就是一种常微分方程求解器,这种求解器采用的是Runge-Kutta解法的 中阶 解法; ode45即Nonstiff(非刚性问题)微分方程式。 注意:大部分情况下,都需要先把高阶微分方程变换成一阶微分方程组的形式进行求解...
然后,在MATLAB中,我们可以定义一个函数来表示这个系统。我们将其命名为"system",输入参数t和Y,输出参数是dY。 function dY = system(t, Y) dY(1,1)=Y(2); dY(2,1)=-2*Y(1)+3*Y(2); end 接下来,我们可以使用ode45函数来求解该微分方程组。 首先,我们需要指定初始条件。令t0为初始时间,Y0为初始...
