Hi,
concerning the roots of:
hJn(x)+xJn'(x)=0 Jn bessel function of order n
a)if h>0 there are real roots.
b)if h=0 there is a double root at x=0
c) If h<0 there is a complex root ix0 and -ix0
For the real roots I have no problem I use findzeros.
My question :how can I find the complex roots of this equation in octave.
I know roots but this is only for polynomials.
Thank you.
