v0.19.0
October 28, 2019➕ Added
.remove_rows_at
andremove_columns_at
which removes a set of rows or columns (specified by indices) from a matrix.

v0.18.2
September 01, 2019 
v0.18.1
August 27, 2019 
v0.18.0
March 31, 2019🚀 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 thegeometry
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
toUnit<...>
andRotation3
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 ofself
bykernel
..convolve_valid(kernel)
returns the convolution ofself
bykernel
after removal of all the elements relying on zeropadding..convolve_same(kernel)
returns the convolution ofself
bykernel
with a result of the same size asself
.
👍 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 L1norm.  Add
.camin()
which returns the matrix component with the smallest L1norm.  Add
.ad_mul(b)
for matrixmultiplication ofself.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 toself.adjoint() * rhs
..gerc(alpha, x, y, beta)
equivalent toself = alpha * x * y.adjoint() + beta * self
.hegerc
which is likegerc
but for Hermitian matrices..syger
which is the new name of.ger_symm
which is equivalent toself = alpha * x * y.transpose() + beta * self
..sygemv
which is the new name of.gemv_symm
which is equivalent toself = alpha * a * x + beta * self
witha
symmetric..hegemv(alpha, a, x, beta)
which is like.sygemv
but witha
Hermitian..gemv_ad(alpha, a, x, beta)
which is equivalent toself = alpha * a.adjoint() * x + beta * self
..gemm_ad(alpha, a, b, beta)
which is equivalent toself = alpha * a.adjoint() * b + beta * self
..icamax()
which returns the index of the complex vector component with the greatest L1norm.
Note that all the other BLAS operation will continue to work for all fields, including floats and complex numbers.
📇 Renamed
RealSchur
has been renamedSchur
because it can now work with complex matrices.
 Add trigonometric functions for quaternions:
