nalgebra v0.22.0 Release Notes

  • 🚀 In this release, we are using the new version 0.2 of simba. One major change of that version is that the 🏗 use of libm is now opt-in when building targetting no-std environment. If you are using floating-point operations with nalgebra in a no-std environment, you will need to enable the new libm feature of nalgebra for your code to compile again.

    ➕ Added

    • The libm feature that enables libm when building for no-std environment.
    • The libm-force feature that enables libm even when building for a not no-std environment.
    • Cholesky::new_unchecked which build a Cholesky decomposition without checking that its input is positive-definite. It can be use with SIMD types.
    • The Default trait is now implemented for matrices, and quaternions. They are all filled with zeros, except for UnitQuaternion which is initialized with the identity.
    • Matrix exponential matrix.exp().
    • The Vector::ith(i, x) that builds a vector filled with zeros except for the i-th component set to x.
