Hoping to find the zero of J0(x) in the interval 0 ≤ x ≤ π, we might try the statement 
 z = fzerotx(@besselj,[0 pi],0)
This is legal usage of a function handle, and of fzerotx, but it produces z = 3.1416. Why? 

It depends on how you implement the function "fzerotx" as John points out. I'm assuming it is a custom function you have written...
