Samples for haverage.m, ver. 2.1.
If version 2.1 of haverage.m is used, the examples of
K. Yagasaki and T. Ichikawa, Higher-order averaging for periodically
forced, weakly nonlinear systems, International Journal of Bifurcation
and Chaos, 9 (1999), 519--531
should be changed as follows:
Section 5.1
<theta,{i,1,5}]
n2=2;m0=5;
haverage[f,barf,{u[1],v[1]},theta,omega,n2,m0]
Section 5.2
<3*theta,{i,1,4}]
haverage[f,barf,{u[1],v[1]},theta,omega/3,2,4]
(If you already typed "<2*theta,{i,1,2}]
haverage[f,barf,{u[1],v[1],u[2],v[2]},theta,omega/2,4,2]
