Has anyone posted an m-file which computes the zeros of bessel functions, J_n and Y_n?

Why not just use FZERO?
zroot = fzero(@(z) besselj(1, z), 3)
besselj(1, zroot) % Should be small

I added a guess for the ith zero of the bessel function of order n
for n =0:5
for i=1:6
guess = 2.5505 + 1.2474*n + (i-1)*pi;
Liste_zeros_Bessel(i,n+1) = fzero(@(z) besselj(n, z),guess);
end
end

The above answer only calculates one zero. However, in most cases, more than one zero is needed.
There are several m.file for finding the zeros of bessel function that U include in here:
Thanks
