In Matlab how we find a in J0(ax)=0 where J0 is bessel function of first kind and zero order, and x is a known vector?

How we can find a as a vector?

If the x vector is not massive, perhaps this inefficient way would work?

syms a;
for i = 1:length(x)
    rt(i) = solve(besselj(0,a*x(i)),a);
end
avec = double(rt);
