一个可行的方式是将所有的多维数组展开(flatten)为一维数组,然而在很多情况下,使用多维数组是最符合本能的直观表示,例如在CFD中使用结构网格表示的流动物理量。另一个可行的调用方法是在Julia端调用时进行两次转置。对于一个既有的大型C程序库,需要针对每个函数作以上的改写和优化,其复杂度也可以想象。 (2) Fortran...
Base.BroadcastStyle(::Type{<:MyType}) = Broadcast.ArrayStyle{MyType}()如果MyType为,则首选AbstractArray。 对于AbstractArrays仅支持特定维度的对象,请创建的子类型Broadcast.AbstractArrayStyle{N}(请参见下文)。 当您的广播操作涉及多个参数时,各个参数样式将合并以确定一个单独的参数来DestStyle控制输出容器的...
“Array{Any}”等, “Any”是Julia语言类型系统的根类型, 相应的数组可以容纳任何Julia对象作为元素。 如果数组元素都是基本类型如Float64, 则不允许给元素赋值为其它类型,如: vf = [1.2, 2.5, 3.6]vf[2] = "abc"## MethodError: Cannot `convert` an object of type String to an object of type Floa...

It aims to ease the different ways to map functions to Julia objects: Arrays, Dicts, and so on. It also provides some tools of functional programming: adverbs, composition, safe-functions and more. Installation For the stable version: ] add https://github.com/TidierOrg/TidierIteration.jl ...
If x and y are arrays, [x, y] will be an array of arrays (#3737, #2488, #8599). using and import are now case-sensitive even on case-insensitive filesystems (common on Mac and Windows) (#13542). Relational algebra symbols are now allowed as infix operators (#8036): ⨝, ⟕...
