Ruby | Vector size() function

Last Updated : 07 Jan, 2020

The size() is an inbuilt method in Ruby returns the number of elements in the vector

Syntax: vec1.size()

Parameters: The function accepts no parameter

Return Value: It returns the number of elements in the vector

Example 1:

# Ruby program for size() method in Vector 
     
# Include matrix  
require "matrix"
     
# Initialize the vector 
vec1 = Vector[1, 2, 3] 
    
# Prints the size of vector 
puts vec1.size() 

Output:

Example 2:

# Ruby program for size() method in Vector 
     
# Include matrix  
require "matrix"
     
# Initialize the vector 
vec1 = Vector[1, 2, 3, 4, 5] 
    
# Prints the size of vector 
puts vec1.size() 

Output:
