⬆️ Update nalgebra requirement from 0.20.0 to 0.21.0 #3

Closed dependabot-preview[bot] closed 4 years ago

dependabot-preview[bot] commented 4 years ago

Updates the requirements on nalgebra to permit the latest version.

Changelog

Sourced from nalgebra's changelog.

[0.21.0]

In this release, we are no longer relying on traits from the alga crate for our generic code. Instead, we use traits from the new simba crate which are both simpler, and allow for significant optimizations like AoSoA SIMD.

Refer to the monthly Rustsim blogpost for details about this switch and its benefits.

Added

  • It is now possible to use SIMD types like simba::f32x4 as scalar types for nalgebra's matrices and geometric types.

Modified

  • Use of traits like alga::general::{RealField, ComplexField} have now been replaced by simba::scalar::{RealField, ComplexField}.
  • The implementation of traits from the alga crate (and well as the dependency to alga_) are now omitted unless the alga cargo feature is activated.

Removed

  • The Neg unary operator is no longer implemented for UnitComplex and UnitQuaternion. This caused hard-to-track errors when we mistakenly write, e.g., -q * v instead of -(q * v).
  • The na::convert_unchecked is no longer marked as unsafe.

[0.20.0]

Added

  • cholesky.rank_one_update(...) which performs a rank-one update on the cholesky decomposition of a matrix.
  • From<&Matrix> is now implemented for matrix slices.
  • .try_set_magnitude(...) which sets the magnitude of a vector, while keeping its direction.
  • Implementations of From and Into for the conversion between matrix slices and standard (&[N] &mut [N]) slices.

Modified

  • We started some major changes in order to allow non-Copy types to be used as scalar types inside of matrices/vectors.

[0.19.0]

Added

  • .remove_rows_at and remove_columns_at which removes a set of rows or columns (specified by indices) from a matrix.
  • Several formatting traits have been implemented for all matrices/vectors: LowerExp, UpperExp, Octal, LowerHex, UpperHex, Binary, Pointer.
  • UnitQuaternion::quaternions_mean(...) which computes the mean rotation of a set of unit quaternions. This implements the algorithm from _Oshman, Yaakov, and Avishy Carmi, "Attitude estimation from vector observations using a genetic-algorithm-embedded quaternion particle filter."

Modified

  • It is now possible to get the min/max element of unsigned integer matrices.

Added to nalgebra-glm

  • Some infinite and reversed perspectives: ::infinite_perspective_rh_no, ::infinite_perspective_rh_zo, ::reversed_perspective_rh_zo, and ::reversed_infinite_perspective_rh_zo.

[0.18.0]

This release adds full complex number support to nalgebra. This includes all common vector/matrix operations as well as matrix decomposition. This excludes geometric type (like Isometry, Rotation, Translation, etc.) from the geometry module.
