# Equazioni differenziali ordinarie

Risolutori di problemi di valore iniziale di equazioni differenziali ordinarie

I risolutori di equazioni differenziali ordinarie (ODE) di MATLAB® risolvono problemi di valore iniziale con diverse proprietà. I solutori possono lavorare su problemi rigidi o non rigidi, problemi con una matrice di massa, equazioni algebriche differenziali (DAE) o problemi completamente impliciti.
