Solve ivp python explication
WebHello, to solve a system of ODEs, I set up a Python-code with solve_ivp as ODE-solver. The solver is calling a function, which generates my ODE-system. Websolve_ivp returns an object from which v ( t) (and other results) can be found, while ode_int returns v ( t). For this single first-order equation, v ( t) is returned for the N requested t …
