This document contains all changes to the crate since version 0.1.8.

0.2.2

0.2.1

Add the rayon feature that enables certain calculations to be done in parallel.
Add the function par_integrate to every quadrature rule struct which can be used when the rayon feature is enabled to perform integration in parallel.
Add the function par_new to GaussLegendre to initialize it in parallel. This function is also behind the rayon feature.

This update is mostly about changing the API to adhere to the Rust API guidelines.

Changed the name of all constructors from init to new.
All constructors now return a Result that contains an error when the input is invalid, instead of panicking. Simply unwrap() it to recover the old behaviour.
The fields of the quadrature rule structs are now private to uphold the invariants needed for integration.
A set of functions have been implemented that access the node and weight data of the quadrature rule structs in various ways.
The nodes_and_weights functions have been removed. To achieve the same effect you can do QuadratureRule::new(...)?.into_node_weight_pairs() if you wish to have a Vec<(f64, f64)> of nodes and their corresponding weights, or you can do QuadratureRule::new(...)?.into_iter().unzip() if you wish to have the nodes and weights separate.
The crate no longer exports the DMatrixf64 type alias.
The crate no longer re-exports the core::f64::consts::PI constant.

Added the serde feature which implements the Serialize and Deserialize traits from serde for all quadrature rule structs.
The quadrature rule structs now store the nodes and weights together in a single allocation. This slightly speeds up integration, and removes one intermediate allocation during creation.
Fixed a sign error in the documentation for GaussJacobi.
