Parameters: The function accepts two mandatory parameters N and M which is the size of the matrix.

Return Value: It returns the zero matrix of size N x M.

Example 1:

# Ruby program for zero() method in Matrix

# Include matrix
require "matrix"

# Initialize a matrix
# using zero method
mat1 = Matrix.zero(4 , 3)

# Print the matrix
puts mat1

Output:

Matrix[[0, 0, 0], [0, 0, 0], [0, 0, 0], [0, 0, 0]]

Example 2:

# Ruby program for zero() method in Matrix

# Include matrix
require "matrix"

# Initialize a matrix
# using zero method
mat1 = Matrix.zero(2, 2)

# Print the matrix
puts mat1

Output:

Matrix[[0, 0], [0, 0]]
