Discretization.
AUTO discretizes ODE boundary value problems
(which includes periodic solutions) by the method of orthogonal
collocation using piecewise polynomials with 2-7 collocation points
per mesh interval (dBSw:73 dBSw:73).
The mesh automatically adapts to the solution to equidistribute
the local discretization error (RuCr:78 RuCr:78).
The number of mesh intervals and the number of collocation points
remain constant during any given run, although they may be changed
at restart points.
The implementation is AUTO-specific. In particular, the choice of
local polynomial basis
and the algorithm for solving the linearized collocation systems
were specifically designed for use in numerical bifurcation analysis.
