Fractional Sine Transform

frst(signal, α, p)

Computing the α order fractional sine transform of the input signal.

Example

julia> frst([1,2,3], 0.5, 2)
3-element Vector{ComplexF64}:
1.707106781186548 + 1.207106781186547im
1.9999999999999998 - 1.7071067811865481im
-1.1213203435596437 - 1.2071067811865468im
