I am trying to find a root to an equation
f[k,...]==0 numerically, where k is the variable I am solving for. Using both
NSove as well as
FindRoot I get the Error:
Encountered non-numerical value for a derivative at t$50961 == 0'.
I am not sure why it talks about
t in the error message, since the variable I am solving for is named
t is the time variable of an integration which is performed inside of the function
f. But for the root finding algorithm that should not be important.
Anyway, I thought that the algorithms Mathematica is trying to apply might not be suited to solve my equation. I thought that nothing could go wrong with the bisection method, but I cannot find it precoded in Mathematica.
I know that it is not hard to code it up. But is there really no precoded bisection method already available?
