Web17 mei 2016 · I am having trouble using the bvp4c with piecewise defined functions. I tested the code and it works fine when the piecewise defined functions are constant. The problem is that I get wrong results in the graph (that I know for sure) in the area where the piecewise defined functions are not constant. Web13 nov. 2024 · I will have to satisfy bvp4c someway or another and looks like it has to be by using more ODEs. Another question I have that can help solve this has to do with the …
How to solve two equations with bvp4c Matlab? - Stack Overflow
WebSolve Equation. If you try to solve the equation directly using e = 10-4, then the solver is not able to overcome the poor conditioning of the problem near the x = 0 transition point. Instead, to obtain the solution for e = 10-4, this example uses continuation by solving a sequence of problems for 10-2, 10-3, and 10-4.The output from the solver in each … Web8 jan. 2024 · f_1 (r) and f_2 (r) are two known functions.
