Julia1.0.5中找不到一些函数!急 (T.T)

初学Julia,处理一段老程序:
以前在0.3版本中有很多矩阵操作的函数找不到了,不知道如何处理?加了线性代数库也没有找到呢。。。
比如atan2,生成单位矩阵的eye,还有——
indmin(返回集合中最小值的索引号)
unshift!(在集合前端插入元素)
请大拿们帮忙支招,非常感谢!

建议看一遍文档,0.3版本太古老了

下个 0.7 不少函数 0.7 都会提示你废弃后该用哪个。

julia> atan2(1.0,2.0)

help?> unshift!
search: unshift!

  No documentation found.

  Base.unshift! is a Function.

  # 1 method for generic function "unshift!":
  [1] unshift!(args...) in Base at deprecated.jl:29

julia> unshift!(1)

太赞了:+1: 版本更新竟然有迹可循,感谢大神还帮忙实践了一下!

确实太古老,调试问题超多,哭了

再次感谢大佬,其他函数替换都OK,刚发现就剩一个shift!,好像是删除操作,在1.0不知道被替换成了什么。请问下您能帮忙看看吗?

┌ Warning: `shift!` is deprecated, use `popfirst!` instead.

非常感谢,您也是0.7版上找到的吗?
