# struct Geode::Vector1(T)

## Overview

Vector containing one component.

Using this type generally doesn't make sense, but it is included to complete some rules and combinations.

T is the scalar type.

## Defined in:

geode/vectors/vector1.cr

## Class Method Summary

• .[](x : T)

Constructs a vector with existing components.

• .[](x)

Constructs a vector with existing components.

## Constructor Detail

def self.new(components : Tuple(T)) #

Creates a vector from its components.

def self.new(array : StaticArray(T, 1)) #

Constructs the vector with pre-existing values.

def self.new(other : CommonVector(T, 1)) #

Copies the contents of another vector.

def self.new(x : T) #

Creates a vector from its components.

def self.new(&) #

Constructs the vector by yielding for each component.

The value of each component should be returned from the block. The block will be given the index of each component as an argument.

``Vector1(Int32).new { |i| i + 5 } # => (5)``

## Class Method Detail

def self.[](x : T) #

Constructs a vector with existing components.

The type of the components is derived from the type of each argument.

``Vector1[1] # => (1)``

def self.[](x) #

Constructs a vector with existing components.

The type of the components is specified by the type parameter. Each value is cast to the type T.

``Vector1F[1] # => (1.0)``

## Instance Method Detail

def to_column : Matrix1x1(T) #

Converts this vector to a column vector, in other words a matrix with one column.

``````vector = Vector1[5]
vector.to_column # => [[5]]``````

def to_row : Matrix1x1(T) #

Converts this vector to a row vector, in other words a matrix with one row.

``````vector = Vector1[5]
vector.to_row # => [[5]]``````

def tuple : Tuple(T) #

Retrieves the components as a tuple.

def x : T #

Retrieves the x component.
