I have the solution of a system stored in a variable sol, which behaves just like a continuous function.
What I need in not just a basic plot(sol, vars=[1 2 3...]) but a plot with the x-axis transformed, i.e. I want to plot \vec y(f(t)) and not \vec y(t). Simply writing function sol1(t); return sol(f(t)); end leads to errors when using plot because sol2 is not the same type as sol, I suppose. (It does work when y is 1-dimensional)
What’s the trick to make it work ?
Thanks !
plot(sol1, vars=[1,2])
leads to
