Algorithm for "stiff" systems #1

Closed aw02m closed 2 years ago

aw02m commented 3 years ago

This program is described with "Simple Shooting Method"[1]. I ask for help to change it to "Multiple Shooting Method". Rossler example is non-stiff, so this program can calculate fixed points, but Extended BVP is not (it's stiff). [1] : Elements of Applied Bifurcation Theory, Kuznetsov, Yuri, pp. 515-517.

This was a very misguided question. To begin with, the Stiff integrator requires the derivative of the equation, which leads to the paradox that "the variational equation itself is needed to compute the value of the variational equation to be taken".
