Hello, I am attempting to run an old script from circa 2003-2004, perhaps written in Matlab 6.5. It calls a bessel function, but not besseli, besselj, etc. I would like to find out which bessel function it was intending to run.I would like to run the function in the current Matlab. Are the old help menus available? Thanks for your help. -Chris

Thanks Walter! That probably solves my problem. However, I didn't see the link, either I am not looking in the right place (I am new to this message board), or you forgot to post that part.

Yes, the documentation for R6.5SP2 is available at https://www.mathworks.com/help/releases/R13sp2/helpdesk.html

However, in that release, there is no bessel() function, as opposed to besseli() and so on.

You need to look back even further, to MATLAB 4.x . In particular, you need to look at http://ftp.task.gda.pl/site/mathworks-toolbox/matlab/specfun/ where you will find MATLAB and FORTRAN source code for the bessel functions for MATLAB in that time frame. You will be able to see that back then bessel() took two parameters and called besselj() with them.
