Euler Angle and Axis

The Euler angle and axis representation is defined by the following immutable structure:

struct EulerAngleAxis{T<:Real}
    a::T
    v::Vector{T}
end

in which a is the Euler Angle and v is a unitary vector aligned with the Euler axis.

Note

The support of this representation is still incomplete. Only the conversion to and from quaternions are implemented. Furthermore, there is no support for operations using Euler angles and axes.
