[ay111]

Examples on the FractionalCalculus.jl home page are returning functions not defined in Julia 1.9.2. For instance,

julia> fracdiff(x->x, 0.5, 1, 0.0001, RLDiffL1()) ERROR: UndefVarError: RLDiffL1 not defined Stacktrace: [1] top-level scope @ REPL[2]:1

Another example:

julia> semidiff(log(x)) ERROR: UndefVarError: semidiff not defined Stacktrace: [1] top-level scope @ REPL[5]:1
