trapezoidal


trapezoidal, a MATLAB code which solves one or more ordinary differential equations (ODE) using the (implicit) trapezoidal method, using MATLAB's fsolve() to handle the implicit system.

Unless the right hand side of the ODE is linear in the dependent variable, each trapezoidal step requires the solution of an implicit nonlinear equation. This version of the code uses MATLAB's implicit equation solver fsolve().
