Ecuaciones diferenciales ordinarias

Mecanismos de solución de problemas de valores iniciales de ecuaciones diferenciales ordinarias

Los mecanismos de solución de ecuaciones diferenciales ordinarias (ODE) en MATLAB® resuelven problemas de valores iniciales con una gran variedad de propiedades. Los mecanismos de solución pueden funcionar en problemas rígidos y no rígidos, problemas con una matriz de masa, ecuaciones algebraicas diferenciales (DAE) o problemas completamente implícitos. Para obtener más información, consulte Choose an ODE Solver.
