Bessel functions, central to many problems in mathematical physics, provide solutions to differential equations that describe wave propagation, heat conduction and vibrations in cylindrical or ...

The JROOT function returns an n ×2 matrix with the calculated roots in the first column and the derivatives in the second column. The inputs to the JROOT function are as follows: is a scalar denoting ...

Bessel beam microscopy, and the techniques that preceded it, are generally used to image live cells in 3D. Bessel beams have a greater capability than other super-resolution imaging techniques for ...
