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 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:
18
Example 2:
# 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:
1
