Sourced from nalgebra's changelog.

[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.

Added

Quaternion and geometric operations

• Add trigonometric functions for quaternions: .cos, .sin, .tan, .acos, .asin, .atan, .cosh, .sinh, .tanh, .acosh, .asinh, .atanh.
• Add geometric algebra operations for quaternions: .inner, .outer, .project, .rejection
• Add .left_div, .right_div for quaternions.
• Add .renormalize to Unit<...> and Rotation3 to correct potential drift due to repeated operations. Those drifts could cause them not to be pure rotations anymore.

Convolution

• .convolve_full(kernel) returns the convolution of self by kernel.
• .convolve_valid(kernel) returns the convolution of self by kernel after removal of all the elements relying on zero-padding.
• .convolve_same(kernel) returns the convolution of self by kernel with a result of the same size as self.

Complex number support

• Add the ::from_matrix constructor too all rotation types to extract a rotation from a raw matrix.
• Add the ::from_matrix_eps constructor too all rotation types to extract a rotation from a raw matrix. This takes more argument than ::from_matrix to control the convergence of the underlying optimization algorithm.
• Add .camax() which returns the matrix component with the greatest L1-norm.
• Add .camin() which returns the matrix component with the smallest L1-norm.
• Add .ad_mul(b) for matrix-multiplication of self.adjoint() * b.
• Add .ad_mul_to(b) which is the same as .ad_mul but with a provided matrix to be filled with the result of the multiplication.
• Add BLAS operations involving complex conjugation (following similar names as the original BLAS spec):
  • .dotc(rhs) equal to self.adjoint() * rhs.
  • .gerc(alpha, x, y, beta) equivalent to self = alpha * x * y.adjoint() + beta * self
  • .hegerc which is like gerc but for Hermitian matrices.
  • .syger which is the new name of .ger_symm which is equivalent to self = alpha * x * y.transpose() + beta * self.
  • .sygemv which is the new name of .gemv_symm which is equivalent to self = alpha * a * x + beta * self with a symmetric.
  • .hegemv(alpha, a, x, beta) which is like .sygemv but with a Hermitian.
  • .gemv_ad(alpha, a, x, beta) which is equivalent to self = alpha * a.adjoint() * x + beta * self.
  • .gemm_ad(alpha, a, b, beta) which is equivalent to self = alpha * a.adjoint() * b + beta * self.
  • .icamax() which returns the index of the complex vector component with the greatest L1-norm.

Note that all the other BLAS operation will continue to work for all fields, including floats and complex numbers.

Renamed

• RealSchur has been renamed Schur because it can now work with complex matrices.

[0.17.0]

Added

• Add swizzling up to dimension 3 for vectors. For example, you can do v.zxy() as an equivalent to Vector3::new(v.z, v.x, v.y).
• Add swizzling up to dimension 3 for points. For example, you can do p.zxy() as an equivalent to Point3::new(p.z, p.x, p.y).
• Add .copy_from_slice to copy matrix components from a slice in column-major order.
• Add .dot to quaternions.
