zeros of bessel functions in scilab

[Belgium 12]

Hi,

I use scilab 5.2.2
Ik have a problem to find the zeros or roots of the bessel functions J0,J1...

Whel I write besselj(0,3) I get the value of the bessel function Jo(3)=0,2600520.

Can someone help me how to find the zeros of these bessel functions in scilab.

Thank you

kind regards
