mittlefferr(α,β,z,ρ)   # evaluate Mittag-Leffler function with tolerance ρ
mittlefferr(α,z,ρ)     # mittlefferr(α,1,z,ρ)

mittleff(α,β,z)   # evaluate Mittag-Leffler function with tolerance eps()
mittleff(α,z)     # mittleff(α,1,z)

Arguments must satisfy α > 0, β real, z real or complex, ρ>0.

For α<1 and/or abs(z)<1, accurate, series-only method are used. The series-only methods work with BigFloat precision for corresponding input types. Some other parameter ranges also use series or asymptotic methods.

For some arguments, integrals are evaluated with quadgk, with no control on errors. Some results are accurate, others are not.

mittleffderiv(α,β,z)   # evaluate derivative of Mittag-Leffler function
mittleffderiv(α,z)     # mittleffderiv(α,1,z)


mittleff fails for some arguments. In particular, some of those that evaluate integrals.
