about use of "dbessel function" in matlab

Kindly tell me that in which version of matlab i can use differentiation of bessel functions "DBESSEL".

[Geoff Hayes]

Ritesh - Is dbessel even a MATLAB function? I can't find any reference to it in the MATLAB help. Where did you see a reference to this function?

It uses besselj, that has probably been a core MATLAB function for the last 20 or so years, so you can likely use it with at least every recent version.
