Ruby | Matrix element() function

Last Updated : 07 Jan, 2020

The element() is an inbuilt method in Ruby returns the element present at the intersection of i-th row and j-th column.

Syntax: mat1.element(i, j) Parameters: The function accepts two parameters i and j which signifies the row_number and column_number. Return Value: It returns the element at mat[i][j].

Example 1:

Ruby

# Ruby program for element() method in Matrix

# Include matrix 
require "matrix"

# Initialize a matrix 
mat1 =  Matrix[[1, 21], [31, 18]]       

# prints the element at 1, 1
puts  mat1.element(1, 1)

Output:

Example 2:

CPP

# Ruby program for element() method in Matrix

# Include matrix 
require "matrix"

# Initialize a matrix 
mat1 =  Matrix[[13, 1, 5], [12, 1, 5], [11, 2, 5]]    

# prints the element at 0, 1
puts  mat1.element(0, 1)

Output:
