Hi Islam,
Thanks for your input
I was able to find all windowing functions; however, there is nothing
about PSD ( power spectral density). In python and matlab, there is
function pwelch which does both windowing and FFT and wondering if there is
the same function in Julia.
Here is simple trial I had but it is complaining about type mismatch
fb= fb[:]*hamming(length(fb))
fb = fft(fb) # take FFT of signal
LoadError: MethodError: `*` has no method matching
*(::Array{Complex{Float64},1}, ::Array{Float64,1})
Closest candidates are:
*(::Any, ::Any, !Matched::Any, !Matched::Any...)
*{T<:Union{Complex{Float32},Complex{Float64},Float32,Float64},S}(!Matched::Union{DenseArray{T<:Union{Complex{Float32},Complex{Float64},Float32,Float64},2},SubArray{T<:Union{Complex{Float32},Complex{Float64},Float32,Float64},2,A<:DenseArray{T,N},I<:Tuple{Vararg{Union{Colon,Int64,Range{Int64}}}},LD}},
::Union{DenseArray{S,1},SubArray{S,1,A<:DenseArray{T,N},I<:Tuple{Vararg{Union{Colon,Int64,Range{Int64}}}},LD}})
*{TA,TB}(!Matched::Base.LinAlg.AbstractTriangular{TA,S<:AbstractArray{T,2}},
::Union{DenseArray{TB,1},DenseArray{TB,2},SubArray{TB,1,A<:DenseArray{T,N},I<:Tuple{Vararg{Union{Colon,Int64,Range{Int64}}}},LD},SubArray{TB,2,A<:DenseArray{T,N},I<:Tuple{Vararg{Union{Colon,Int64,Range{Int64}}}},LD}})
