After some months of hard work, I am thrilled to announce the release of the v1 of `StructuralVibration.jl`.

In this release, I have polished the API to be consistent across the package, but also with SciML conventions. But the major addition to the package is a whole set of functions related to Experimental analysis (EMA). Among those, one can mention:

- Sdof methods (peak picking, Nyquist circle and least-squares fit)
- Mdof methods (Least-squares complex exponential, Least-squares complex frequency, Polyreference least-squares complex frequency)
- Stabilization diagram
- Quality and analysis indicators
- FRF reconstruction

For the complete list, you can read the [online documentation](https://maucejo.github.io/StructuralVibration.jl/).

As usual, PRs and issues are welcome!

Finally, the package is referenced on [Zenodo](https://zenodo.org/records/17431718) for citations 😉

Congratulations!  
great documentation. What did you use to generate it? It doesn’t look like Documenter.jl

As mentionned by @zdenek_hurak, I use Quarto, because I already use it for publishing my lecture notes. It is very easy to use and very well documented.

v1.1.0 has just been released!

It contains some nice additions related to Operational Modal Analysis. I have implemented Stochastic System Identification methods and extended the EMA algorithms to deal with half-spectrum. Don’t hesitate to read the [release notes](https://maucejo.github.io/StructuralVibration.jl/overview/release_notes.html) for a description of the changes.

v1.10.0 is out! This new release adds two extensions for manipulating meshes and animating a structural field (kinematic field, mode shape, ODS, …). These extensions requires Makie.jl and Meshes.jl.

A word of caution though. This update is limited to surface/boundary meshes (i.e. using triangular or quadrangular elements), because these extensions have primarily been developed for experimental modal analysis (EMA and OMA).
