Hi I'm brand new to maxima, and I hope it is okay to ask questions on this
mailing list.
I'd like to use evolution2d
( see http://maxima.sourceforge.net/docs/manual/en/maxima_50.html)
to look at iterations for a flow with a certain time step.
or phi_t(phi_t(xo)) = phi_2t(xo) etc
What I tried was integrating the ODE to the required time where x is my
initial condition then picking out the last value. (Notice the apostrophe
in front of last and rk)
define(f(x),'last('rk(exp(-t) + u, u,x,[t,2,7,0.01]))[2]);
If I type say f(-0.1),nouns I do get the answer I'm looking for but
I've been unable to put this line into a functions. For instance I tried
g(x) := nouns(f(x)) and define(g(x), (f(x),nouns)) but no success.
I'd appreciate any help and also if someone can think of a better way to
approach this problem I'd appreciate it.
Thank you,
Steve
