Plots of zeroJ0.y and zeroJ1.y should display steps with lower-right corners at ( t , y ) = ( x_i,Modelica , x_i,GSL ) and such values should be equal at these corners.

The location of the zeros of Bessel functions is a crucial element in some boundary value problems involving cylindrical symmetry and this example shows how the 'Bessel_zeroJnu' block (with nu=n; n integer) provides said info quickly.

As not all special functions' zeros are provided via GSL routines, the displayed use of Modelica's zero-crossing logical blocks could be useful for finding such information for these other functions.
