我想创建一个函数struct valueStruct
a::Vector{Float64}
a2::Vector{Float64}
end
values = valueStruct(ones(10), ones(10));
values2 = 1:10;
function testFunc!(values, values2)
values.a .= values.a .* values2;
end
，以便它可以接受testFunc2!而不是整个对象。例如：field。但是，我一直收到这个错误：
testFunc2!(values.a, values2)。
我想这样做，因为在我的实际代码中，我想在结构LoadError: LoadError: syntax: "values.a" is not a valid function argument name的循环中递归地应用testFunc!，例如values。我知道我可以这样做：
testFunc!(values.a2, values.a)但是，这不是我想要的。在我的实际代码中，我需要一个灵活的函数，以便我可以将它应用于一个类型的字段。这可能吗？
答案 0 :(得分：1)
我不明白这个问题。这很好用：
struct ValueStruct
a::Vector{Float64}
a2::Vector{Float64}
end
function testfunc!(a, b)
a .*= b
end
values = ValueStruct(ones(10), ones(10))
values2 = 1:10
testfunc!(values.a, values2)
顺便说一句：朱莉娅有一个强烈的惯例，即类型名称应该大写：ValueStruct，而不是valueStruct。还有一个约定，函数名称应全部小写，但似乎不那么严格。
