Julia Notes Day by Day
Functions ∑(n) = sum(1:n) ∑(3) # Output: 6 ∑(100) # Output: 5050 Unicode variable and function names ∑ are allowed. Julia functions can be defined using compact "assignment form" syntax. The value returned by a function is the value of the last ex...
Char and String A Char value represents a single character c = 'x' d = Int('x') # 120 e = Char(120) # 'x' f = '\u2200' # '∀': Unicode U+2200 (category Sm: Symbol, math) g = 'A' + 1 # 'B' String literals are delimited by double quotes or triple doub...
Composite types are called records, structs, or objects in various languages. struct Foo bar baz::Int qux::Float64 end foo = Foo("Hello, world.", 23, 1.5) # Foo("Hello, world.", 23, 1.5) foo.bar # "Hello, world." Composite objects dec...
Module Modules in Julia help organize code into coherent units. They are delimited syntactically inside module NameOfModule ... end.Typically, in larger Julia packages you will see module code organized into files, eg module SomeModule # export, usi...
Install Julia All official Julia binaries produce portable installations. Once installed, the directory in which Julia was installed can be moved to a different location on the same computer, or even to a different computer. wget https://julialang-s3...
