fourieranalysis.jl's Issues

update project dependencies

this is a wonderful library indeed, thanks for putting it together. Unfortunately, it seems to downgrade my libs, such as DataFrames to 0.19. I think it is coming from one of the imports.

do you think its possible to upgrade the project dependencies?

thanks
Rohit

Question about coherence

Hi,

Forgive me about my ignorance in Fourier analysis. I have some questions about computing coherence and cross-spectrum and whether or not this package provides such functionalities.

I want to perform some analysis similar to the wavelet coherence as demonstrated in the link to MATLAB's documentation. Simply speaking, given two time-series x and y, I want to compute the correlation coefficients in the time-frequency domain. However, it seems to me that the word "coherence" and "cross-spectral" in Fourier analysis refer to cross-correlations, which I am not sure if that's what I'm looking for.

Do you know if it's possible to perform my desired analysis with this package?

README demo not working

Hi,

Thanks for building and sharing this package!

I tried to run the example in README.md, but something is not working:

t in randn(t*16, 4) not defined
After I replaced t with wl

julia> heatmap(A)
ERROR: Cannot convert TFAmplitude to series data for plotting

please update compat of deps

AbstractFFTs, FFTW, PosDefManifold, and RecipesBase all have newer versions released than your Project.toml specifies is compatible. i would submit a PR to update the compat section of your Project.toml, but there are no tests for FourierAnalysis! so i wouldn't know if anything broke. could you please do so? thanks.

Plots as an optional dependency?

How would feel about making Plots.jl an optional dependency? This should be easy to do using Requires.jl.

Thanks for any recommendations to succeed.

sampling rate requires integer value

I have a time series that I want to analyze, where the sampling time is 1.52 s and the sampling rate is therefore 1/1.52 Hz. Why is the parameter sr of spectrum() required to have integer value? Did I misunderstand something?

Missing FFTW import

Hi again,

In the spectra demo, plan_rfft comes from FFTW.jl, but the package is not imported.

FourierAnalysis.jl/src/spectra.jl

Line 158 in ac11cda

# using FFTW.jl only

Just below this line, Plots.jl are imported twice.

It's great that these examples are organized in a natural order! However, some parts seem to be independent of each other, and if I blindly copy and paste the whole chunk into the REPL, interesting intermediate outputs are missing. I don't know if there are better ways to handle these demos 🤔

Corrupt Package

Installing this package has made Plots and DifferentialEquations no longer work in my Julia. This error does not resolve after installing/reinstalling Julia
