From the series: Solving ODEs in MATLAB ODE45 is usually the function of choice among the ODE solvers. It compares methods of orders four and five to estimate error and determine step size. ODE45 is so accurate that its default behavior is to use its interpolant to provide results at inter...
Important algorithms and design decisions of a new code, ode15i, for solving 0 = F(t, y(t), y鈥 (t)) are presented. They were developed to exploit Matlab, a popular problem solving environment (PSE). Codes widely-used in general scientific computation (GSC) compute consistent initial ...

Open in MATLAB Online Hi all, I'm working on a problem where I have to solve a nonlinear 2nd order ODE with initial conditions. I have to solve this ode for a set of constants (a, b, c) that coorespond to unique initial values and all are passed into my function as 1xN arrays....
Open in MATLAB Online I have an ode (2*A*k + 3*G*h(t)^(1/2))*diff(h(t), t) == 2*G*h(t)*(h(t)^(1/2) + (A*k)/G) that I need to plot as h(t) vs t. ODE45 (and ODE23) returns: Undefinedfunction 'exist' for input arguments of type 'sym'. ...
