Initial conditions of the ODE
InitialConditions = [y1(t0), y2(t0), …] sets the initial conditions for the initial value problem
TimeMesh = [t0, t1, t2, …] sets the values of the independent variable t (the "time") of the ODE at which graphical points of the solution curve are plotted. The first entry t0 is the initial time for which initial conditions are set by InitialConditions.
We solve the initial value problem numerically:
f := (t, Y) -> [-Y]: Y0 := : timemesh:= [0, 0.2, 0.5, 1, 1.5, 2, 3, 5]: plot(plot::Ode2d(f, InitialConditions = Y0, TimeMesh = timemesh))
delete f, Y0, timemesh:
