Vectors

(import (otus algebra))

Vector is a one-dimensional array. Vector can be declared using several ways:

• by it's values which can be any applicable number:

> [1 2 3 4 5]
#(1 2 3 4 5)

> [0 -3 3/7 16+4i 7.12 (inexact 7.12) 123456789876543213546576666777757575757444]
#(0 -3 3/7 16+4i 178/25 7.12 123456789876543213546576666777757575757444)

• As a copy of existing vector:

> (define v [1 2 3 4 5])
> (print v)
#(1 2 3 4 5)
> (copy v)
#(1 2 3 4 5)

• As an uninializied vector of N elements.

> (vector 14)
#(0 0 0 0 0 0 0 0 0 0 0 0 0 0)

• As a vector of 0s:

> (zeros 14)
#(0 0 0 0 0 0 0 0 0 0 0 0 0 0)

• As a vector of 1s:

> (ones 42)
#(1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1 1)

• As a vector of a same any applicable value:

> (fill (vector 17) -33)
#(-33 -33 -33 -33 -33 -33 -33 -33 -33 -33 -33 -33 -33 -33 -33 -33 -33)
