Last Updated : 12 Jul, 2025

The row() is an inbuilt method in Ruby returns a vector that contains all the elements in the given row-number.

Syntax: mat1.row(num) Parameters: The function takes a mandatory parameter row, whose elements are to be returned in a vector. Return Value: It returns a vector containing all the elements in the num row.

Example 1:

Ruby

# Ruby program for row() method in Matrix

# Include matrix 
require "matrix"

# Initialize a matrix 
mat1 = Matrix[[6, 432], [54, 323]]  

# Prints the 0th row 
puts  mat1.row(0)

Output:

Vector[6, 432]

Example 2:

Ruby

# Ruby program for row() method in Matrix
 
# Include matrix 
require "matrix"
 
# Initialize a matrix 
mat1 = Matrix[[1, 1, 1],[2, 2, 2],[3, 5, 6]]  
 
# Prints the 1sr row 
puts  mat1.row(1)

Output:

Vector[2, 2, 2]
