function f=besjz(n,r);
%> besjz.m calculates the real zeros of besselj(n).
%> Call besjz(n,r)
%> Input: n > 0 is a real number, r > 0 is an integer
%> Output:  the r first zeros of besselj(n) as a column vector.
%> Uses <zed.m> and <zeroai.m> to get a zero-order approx for n > 0.
%> Consult Handbook of Mathematical Functions Sect 9.5 for the theory.
