The inner_product() is an inbuilt method in Ruby returns dot product of given vectors.

Syntax: vec1.inner_product(vec2)

Parameters: The function accepts a single vector as parameters

Return Value: It returns dot product of given vectors 

Example 1:  

Ruby

#Ruby program for inner_product() method in Vector

#Include matrix
require "matrix"

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

#Prints the dot product of vectors
                          puts vec1.inner_product(vec2)

Output: 

4

Example 2: 

Ruby

#Ruby program for inner_product() method in Vector

#Initialize the vector
    vec1
    = Vector[1, 2, 3] vec2 = Vector[2, 1, 4]

#Prints the dot product of vectors
                             puts vec1.inner_product(vec2)
