This was supposed to fix #36. Although in the end
@code_warntype fftshift(rand(ComplexF64,64,64))
shows no problems on the latest Julia (although it does print a bit less with this PR) and isn't fixed on Julia 1.0!It also adds a method for
copy(fftfreq(8))
, this previously gave an Array, whereas now it behaves likecopy(1:8)
. I thinkcollect(1:8)
orArray(1:8)
are the ways to make an Array.
