[julia-users] Re: small array/vector ops with broadcast and generators?

If your code consists mainly of small arrays, you may want to have a look at the FixedSizeArrays or StaticArrays package. These provide fast and convenient stack allocated arrays. On Sunday,

For functions like dot and norm, its also good to check out all the existing methods in base, via e.g. methods(norm). You'll get this response: # 9 methods for generic function "norm":
