numpy - ODE in python with specific time point -


i explain question , reach problem @ end of ezplanation. in order solve function f ode python @ first must set initial point or initial condition (x0=0.2). then, according codes have searched on internet , sources, should choose rage(time point) solving , plotting. examplet=np.linspace(0,5,20) devides range between 0 5 20 sections , have 20 out puts.

    sol=odeint(f,x0,t)

... problem is, have 1 out put @ 1 time point, set initial point example x0=0.2, want have 1 answer @ specific point choose, example @ point of 3.4. when plot ode have answers first point final point, want have optional choice set specific points instead of using linspace(min, max,n)

i appreciate , thank attention.

the t argument can contain 2 points, first element being time value of x0 (the initial condition), , second being final time interested in.

t0 = 0 t1 = 123.45  # final time interested in sol = odeint(f, x0, [t0, t1])

then values @ time t1 x1 = sol[-1].

if time span between t0 , t1 long enough, solver might make maximum allowed number of internal steps before reaching t1. limit can changed mxstep argument.
