I dont want to find all zeros of this function by using 'bessel function' besselj(nu, Z) in matlab toolbox. I would like to create a matlab function to calculate all roots. I create a function on newton iteration method, but it calculated just one root. thanks for your helps in advance.

There are also techniques that involve splitting up the interval into a number of subintervals and running a Newton type algorithm on the entire vector of starting points, and then at the end taking the unique values (taking into account round-off error). This approach only really works if you have information about the minium separation of the zeros.
