# Does the set of Hermitian Wavelets include fractional derivatives?

According to Wikipedia, Hermitian wavelets, "The $$n^{{\textrm {th}}}$$ Hermitian wavelet is defined as the $$n^{{\textrm {th}}}$$ derivative of a Gaussian distribution."

Are the wavelets defined by non-integer values of $$n$$ included in this set, or are they members of a superset of this?
