I tried to evaluate the function

convert(BesselJ(nu, x), FormalPowerSeries)

only to obtain the Error message

Error, (in convert/FormalPowerSeries) input contains no or more than one variable.

Seems a rather strange error. I thought it would treat x as a single variable

Is there a Maple Support Update package for Maple 2025 ? If so, how do I download it?

Thanks, Roy

I have a rather involved double summation which I am trying to evaluate for various values of the four parameters. Is there a straightforward way that Maple can evaluate this summation?

For example, lambda=nu= +1/2 and/or -1/2 and kappa=mu=1/2 for a start. I would like an expression as a .mw file into which I could put various values and get varying degrees of simplification, rather than trying to do "handraulic" evaluations.

Is the Wigner Ville transform implemented in Maple or its' Toolboxes?

I recently attempted to Fourier Transform the LommelS1 function using Maple. After loading

restart;
with(inttrans);
[addtable, fourier, fouriercos, fouriersin, hankel, hilbert, invfourier, invhilbert, invlaplace, invmellin, laplace, mellin,   savetable, setup]

the command did not work on LommelS1, after several attempts. I then used the 1F2 hypergeometric definition of LommelS1, and tried
fourier (t^(mu + 1)*hypergeom([1], [3/2 + nu/2 + mu/2, 3/2 - nu/2 + mu/2], -t^2/4)/((mu - nu + 1)*(mu + nu + 1)), t, w)

and after about 6 attempts of restart thru to fourier(...), it finally gave me about 30 lines of output, which simplified to about 8 lines, then subsequently simplified symbolically to two final lines of output- but I haven't been able to reproduce the result since (after about 20 attempts), so it really makes me question the algorithm, its implementation and its stability, or am I missing something here??
