I am using
FindRoot to find the root of a function, say
f(x), and going through a loop for different values of
x. The function has no root for certain values of
x, so there is an error which is thrown saying
"Failed to converge to the requested accuracy or precision within 100 iterations."
I read that when this happens, Mathematica gives
x the value at which it was at when the maximum iterations was achieved. Is there a way to make
x equal to
Null when the maximum number of iterations is achieved?
