[Maxima-discuss] proposal to rename gamma_greek to gamma_incomplete_lower

[Robert D. <rob...@gm...>]

gamma_greek is the lower incomplete Gamma function, i.e. the tail from 0
to something. Maxima also has gamma_incomplete which is the upper
incomplete Gamma function, i.e. the tail from something to inf. 

I'd like to propose that gamma_greek be renamed to
gamma_incomplete_lower. What does anyone think of that?

I don't know if we should rename gamma_incomplete to
gamma_incomplete_upper. I'm inclined to let it stand.

I guess we could outfit gamma_greek so that some kind of warning is
printed the first time it is encountered, to encourage users to use
the new name instead. I'm not too crazy about such schemes, but we have
usually done something like that before, so maybe it's expected to some
extent.

I don't know how the function came to be named gamma_greek, and to be
honest, I don't really care to sort it out.
