Scipy bvp
Did you know?
WebThe disadvantage of the method is that it is not as robust as finite difference or collocation methods: some initial value problems with growing modes are inherently unstable even though the BVP itself may be quite well posed and stable. Consider the BVP system The shooting method looks for initial conditions X(t_ 0)==c so that G==0.
