ndspec 0.1.1

//! # ndspec
//!
//! `ndspec` is a crate for working with energy density spectra with a focus on ocean waves, wind, and related response spectra.
//!
//! The crate is organised into the following modules:
//!
//! * `core` - Core functionality for working with energy density spectra.
//! * `waves` - Functions for calculating energy density spectra for ocean waves.
//! * `wind` - Functions for calculating energy density spectra for wind.
//! * `spectrum` - provides the Types `Spectrum1` and 'Spectrum2' for one-dimensional and two-dimensional spectra respectively.
//!
//! All wave and wind spectra can be converted into either a `Spectrum1` or
//! `Spectrum2` Type. These types provide various traits for working
//! with and evaluating energy density spectra.
//!
//! The crate is designed to be used in conjunction with the `ndarray`
//! crate. The `ndarray::Array1` and `ndarray::Array2` types are
//! underlying data structures adopted throughout.
//!
//! The crate also provides a Python extension that can be compiled and installed seperately.
//!
//! ## Installation
//!
//! Add the following to your `Cargo.toml` file:
//!
//! ```toml
//! [dependencies]
//! ndspec = "0.1.0"
//! ```
//!
//! ## Usage
//!
//! The following example demonstrates how to calculate the energy density spectrum for a Bretschneider wave spectrum:
//!
//! ```
//! use ndspec::prelude::*;
//!
//! let hs = 1.5;
//! let tp = 18.0;
//! let mut bretschneider = Bretschneider::new(hs, tp);
//! let omega = Array1::linspace(0.1, PI, 100);
//! let energy = bretschneider.set_omega(omega).energy();
//! ```
//!
//! ## Python Extension
//!
//! The crate provides a Python extension that can be compiled and
//! installed seperately. To build the extension, `maturin` is
//! required and the `python-extension` feature must be enabled:
//!
//! ```bash
//! maturin build --release --features python-extension
//! ```
//!
//! and install with `pip`.
//!
//! ### Examples
//!
//! Define a Jonswap energy density spectrum from only Hs and Tp,
//! convert to a `Spectrum1D` type, and then evaluate the most probable
//! maximum amplitude over a 3 hour (10,800 s) time window:
//! ```python
//! import ndspec
//! S = ndspec.Jonswap(hs=1.5, tp=10.0).to_spec1d()
//! print(S.Ampm(10_800))
//! ```
//!
//! Print out the help for the Jonswap class in Python::
//! ```python
//! import ndspec
//! help(ndspec.Jonswap)
//! ```
//!

/// ## The prelude
///
/// The purpose of this module is to:
/// * define the namespace
/// * keep all imports in a central location
/// * help avoid the direct imports of traits defined by this crate in the parent module
/// * provide a convenient and consistent way to import the main types, traits, and functions with a single import
/// * provide access to useful external crate types and traits from a single import
///
/// ## Example:
///
/// ```
/// use ndspec::prelude::*;
/// ```
