After I got this error with 7251, again I did a Clean re-installation, and all issues posted later occurred consequent to this.

Furthermore, a similar Clean re-installation of 7251 was done in my second laptop today, but errors continued to occur with same test worksheets except Jean's "Test_Gamma_7251_[6179].sm".

Therefore, I have no alternative but leave it to the developers to decide.

Wait and see what Grand Doctors have to say.
Frechet PDF is another one that Simpson rejects.
In the attached, rescued in two ways.
When compatible, dn_GearsBDF is hyperfast, known accurate.
Thanks Collab for your contribution, most interesting.
Cheers ... jean

It carries parameters as well, following a fitting session.

Observed same problems even after a second Clean re-installation of 7251.
Consequently, I noticed that the Vectorize operator works correctly
when eval() function is used to evaluate alpha and beta of the Gamma function.
Otherwise, it gives incompatible results.
Has anybody experienced this issue?
Thank you Jean for the inspiration and encouragement.
Thank you Alvaro.
Any comments?

Hi Nugegodage. I slightly modify your file, putting eval only where Mean appear. What I see rigth now, with your new file using eval, not before, is that there are not bug, and the "bad results" are because Mean can't be vectorized (or better say, isn't a good idea vectorize them), like any other function that take vectors or matrices as arguments.

Not clear what's incompatible in the yellow/red brace.
