例如,我发现 Distance 包中的 Euclidean distance 不适用于 Unitful vector;还有人发现 Julia 运行外部命令的函数不适用于 substring,Julia 对缺失值的支持在某些情况下会破坏矩阵乘法,标准库的 @distributed 宏不适用于OffsetArrays... 尤其是 OffsetArrays 被证明是 correctness bug 的重要来源。这个包提供了一种数组...
function clear!(vector::Vector, range) vector[range] .=0 nothing end Julia 的函数传参对非基本类型都传引用,也就是说在内部修改可变结构,外部能收到这个变化。对于会修改入参(不纯)的函数,建议以 ! 结尾作为警示。这里把 clear! 单独抽出来是为了方便试不把阻带置 0,而是做某些均衡的效果。 注意,Jul...

Constructs which create uninitialized memory should only be used if there is a demonstrated performance impact and it should ensure that all memory is initialized in the same function in which the array is intended to be used.Example:function make_array(n::Int) A = Vector{Int}(undef, n) #...
