There are probably others, but here are a few of them that I know
about:
%he[n] (z) Hermite polynomial (Nota bene: `he', not `h'. See A&S 22.5.18)
hstruve[n] (z) Struve H function
lstruve[n] (z) Struve L function
%f[p,q] ([], [], expr) Generalized Hypergeometric function
gammagreek(a,z) Incomplete gamma function
gammaincomplete(a,z) Tail of incomplete gamma function
slommel
%m[u,k] (z) Whittaker function, 1st kind
%w[u,k] (z) Whittaker function, 2nd kind
erfc (z) Complement of the erf function
ei (z) Exponential integral (?)
kelliptic (z) Complete elliptic integral of the first kind (K)
%d [n] (z) Parabolic cylinder function
These are taken from the help for specint. (There are many others in
the source code for specint.) Actually, I don't think maxima can
currently evaluate any of these numerically. What maxima knows about
these functions is very limited or non-existent.
