From the series:Solving ODEs in MATLAB ODE1 implements Euler's method. It provides an introduction to numerical methods for ODEs and to the MATLAB suite of ODE solvers. Exponential growth and compound interest are used as examples. Related MATLAB code files can be downloaded from MATLAB Central...
From the series: Solving ODEs in MATLAB ODE2 implements a midpoint method with two function evaluations per step. This method is twice as accurate as Euler's method. A nonlinear equation defining the sine function provides an example. An exercise involves implementing a related trapezoid method...
I would like to solve an ordinary differential equations (ODE) with a specfic step using the command ode45. The equation has a range between 0 and 2.75 and the intial condition is 1 F=@(R,t)((R/t_a)*((CFS(1,i))/(0.25*taw_0)-R)) [t,R]=ode45(F, [0 2.75], 1) In ...
From the series: Solving ODEs in MATLAB ODE4 implements the classic Runge-Kutta method, which is the most widely used numerical method for ODEs over the past 100 years. Its major shortcoming is the lack of an error estimate. A simple model of the growth of a flame is an example that ...

Open in MATLAB Online Hello everyone. I'm trying to solve in Matlab2017b an ODE with the boundary conditions: , For this purpose, I have used the solver bvp4c. I think that this equation must be solvable for all values of [z1 z2 z3] because it has the form of a generic force...
To solve this equation numerically, we need to reformulate it so that it can be handled by MATLAB's numerical solvers, which require the derivative to be isolated on one side of the equation. Since we cannot isolate
