New variable bindings on each for loop and comprehension iteration (#1571). For example, before this change: julia> map(f->f(), { ()->i for i=1:3 }) 3-element Any Array: 3 3 3 and after: julia> map(f->f(), { ()
Julia 有一个基于 LLVM 的 JIT 编译器,这让使用者无需编写底层的代码也能拥有像 C 与 FORTRAN 那样的性能。因为代码在运行中编译,你可以在 shell 或 REPL 中运行代码,这也是一种推荐的工作流程。 Julia 是动态类型的。并且提供了为并行计算和分布式运算设计的多重派发机制。 Julia 自带包管理器。 Julia 有许多...
function _getmeta(body::Array{Any,1}, sym::Symbol, delete::Bool) idx, blockargs = findmeta_block(body, args -> findmetaarg(args,sym)!=0) if idx == 0 return false, [] end metaargs = blockargs[idx].args i = findmetaarg(blockargs[idx].args, sym) if i == 0 return false,...
虽然Douglass.jl刚写完没多久,jmboehm本人也还在进一步开发,但目前已经可以执行Stata多个主要命令,比如: generate-- Creates a new variable and assigns the output from an expression to it. replace-- Recplaces the content of a variable, but does not change the type. egenerate(oregenfor short) -- Cre...

Linear Regression is a fundamental machine learning algorithm used to predict a numeric dependent variable based on one or more independent variables. The dependent variable (Y) should be continuous.In this tutorial I explain how to build linear regression in Julia, with full-fledged post model-...
