Ruby | Vector – method

The – is an inbuilt method in Ruby returns the subtraction of two vectors 

Syntax: vec1 – vec2
Parameters: The function does not accepts any parameter.
Return Value: It returns the subtraction two vectors.

Example 1: 

CPP

#Ruby program for - method in Vector

#Include matrix
require "matrix"

#Initialize the vectors
    vec1
    = Vector[1, 2] vec2 = Vector[1, 4]

#prints the new vector
                          puts vec1
                          - vec2

Output:  

Vector[0, -2]

Example 2: 

CPP

#Ruby program for - method in Vector

#Include matrix
require "matrix"

#Initialize the vectors
    vec1
    = [ 1, 4, 5 ] vec2 = [ 1, 4, 7 ]

#prints the new vector
                         puts vec1
                         - vec2

Output: 

Vector[0, 0, -2]
