请问各位老师，求一组数的最大值及其位置用max函数吗？什么格式呢？
julia> max(2,5,7,1)
7
julia> a=[1 3 9 4 7 8 5];
julia> max(a)
ERROR: MethodError: no method matching max(::Matrix{Int64})

可以采用findmax（）
a=(1,3,9,4,7,8,5)
findmax(a)
输出：(9, 3)
（最大值,位置）
进一步使用可以查阅findmax的帮助文件。

在Syslab中，max函数是返回输入参数的最大值，如
Julia> max(1,3,9,4,7,8,5)
9
如果要返回集合最大值，使用maximum函数，如
Julia> a=[1 3 9 4 7 8 5]
Julia> maximum(a)
9
