Cortex
Cortex is a programming language for scientific computing built on the Cortex Compute Engine.
The Cortex language is a work in progress. The information below reflects the current thinking and may change.
Here is “Hello World” in Cortex:
"Hello World"
Here are a few more examples:
Simplify(2 + 3x^3 + 2x^2 + x^3 + 1)
// ➔ 4x^3 + 2x^2 + 3
x = 2^11 - 1
"\(x) is a \(Domain(x))"
// ➔ "2047 is a PrimeNumber"

Dictionaries
A dictionary is a collection of set of key/value pairs separated with a comma
(,) and surrounded by curly brackets.
Elements in a dictionary are not ordered and the keys are unique. They are iterable and indexable by the key value.
A key/value pair is a string, followed by -> and by an expression. If the
string does not contain a character with a White_Space or Pattern_Syntax
Unicode property the quotation mark around the string can be omitted. Note that
if the quotation mark is omitted the character escape sequences are not applied.
{one -> 1, two -> 2}
{"one" -> 1, "two" -> 2}
The empty dictionary is {->}.
Lists
A list is a collection of expressions separated with a comma , and surrounded
by square brackets: [ and ]
Elements in a list are ordered and don’t have to be unique. They are iterable and indexable with a numeric value (their order in the list, start with 0).
[3, 5, 7, 11]
[3, 3 + 5, 3 + + 7, 3 + 5 + 7 + 11]
The empty list is [].
Sets
A set is a collection of expressions surrounded by curly brackets: { and }.
Elements in a set are not ordered and must be unique. They are iterable but they are not indexable.
The empty set is {}.
