FixedSizeArrays.jl is a package for the Julia programming language which implements mutable fixed-size arrays (FixedSizeArray), which means the length of the array can not change after construction and is amenable to be constant-propagated at compile-time when possible.
FixedSizeArrays supports the standard array interfaces, so things like broadcasting, matrix multiplication, other linear algebra operations, similar, copyto! or map should just work.
