我想导出一个大概2400*30000的纯数字数组，之前是这样导出的
CSV.write("E:/test.csv", DataFrame(xyz))
BoundsError: attempt to access 4194304-element Array{UInt8,1} at index [1:4194305]
throw_boundserror(::Array{UInt8,1}, ::Tuple{UnitRange{Int64}}) at abstractarray.jl:484
checkbounds at abstractarray.jl:449 [inlined]
view at subarray.jl:147 [inlined]
writecell(::Array{UInt8,1}, ::Int64, ::Int64, ::IOStream, ::Int64, ::CSV.Options{UInt8,UInt8,Nothing,Tuple{}}) at write.jl:148
macro expansion at write.jl:183 [inlined]
eachcolumn at utils.jl:49 [inlined]
但是容易出错，花的时间还长，不知道有没有什么更快更好的方法啊
