In the past I was using *
for SeitzOperator
s' operations:
Base.:*(m::SeitzOperator, c::CrystalCoord) = CrystalCoord((m.data*[c; 1])[1:3])
Base.:*(a::SeitzOperator, b::SeitzOperator) = SeitzOperator(a.data * b.data)
But they can be ambiguous: where is
Base.:*(c::CrystalCoord, m::SeitzOperator)
?
Besides, I need to define a type CrystalCoord
. But then I realized I could just use function-like objects onto an AbstractVector
:
(::SeitzOperator)(v::AbstractVector)
which follows CoordinateTransformations.jl
design.
It's more common to use degrees instead of radians in crystallography. Besides, sin
and cos
on floating point number is less accurate.
