Question

如何在Julia中将元素附加到二维数组？我尝试使用push!

test = [1 2; 3 4]
push!(test, [8 9])

但是我遇到了以下错误

ERROR: MethodError: no method matching push!(::Array{Int64,2}, ::Array{Int64,2})
Closest candidates are:
  push!(::Any, ::Any, ::Any) at abstractarray.jl:2158
  push!(::Any, ::Any, ::Any, ::Any...) at abstractarray.jl:2159
  push!(::Array{Any,1}, ::Any) at array.jl:920
  ...
Stacktrace:
 [1] top-level scope at none:0

谢谢！

您可以通过串联其他行来实现。

test = [1 2; 3 4]
vcat(test, [8 9])
