Create Sequence

Here's an example to create the arithmetic sequence via hipparchus:


use hipparchus_seq::Sequence;

let v = Sequence::Arithmetic { init: 1, difference: 1 }.vec(5);

Below is a full list of all sequences hipperchus has supported:

Sequence Syntax Feature
Arithmetic { init:T, difference:T } arithmetic sequence with init value and difference
Geometric { init:T, ratio:T } geometric sequence with init value and ratio
Natural (bool) natural sequence starting with 0/1
Odd - odd sequence starting with 1
Even (bool) even sequence starting with 0/1
Power (T) power sequence starting with 1 with radix
Triangular - triangular sequence starting with 1
Square - square sequence starting with 1
Cubic - cubic sequence starting with 1
Harmonic { init:T, difference:T } harmonic sequence with init value and difference
Fibonacci - fibonacci sequence starting with 0, 1
Lucas - lucas sequence starting with 2, 1
Padova - padova sequence
Catalan - catalan sequence
LookAndSay (usize) look and say sequence starting with a usize value

And hipparchus-mean support recursive, map and fold OPs to generate complicated or derived sequences. Please refer to codes written in unit tests of sequence module.
