Doing this well in a .mfile is a very big job. You are better off using
the Bessel function suite from our FTP suite, which you already have.
You do not have to put the new Bessel functions in the toolbox/matlab/specfun
directory. You can put them in a directory that belongs to you if you
arrange to have that directory name ahead of specfun on your MATLAB path.
Or, just work in the directory that contains the new functions.
