input: Write a function to generate a 3x3 matrix of random integers within the range of 1 to 5 using the NumPy library. The function should print the generated matrix.
  import numpy as np
  
  def generate_random_matrix():
      a = np.random.randint(1, 6, size=(3,3))
      print(a)
  
  generate_random_matrix()
output: import numpy as np
  
  def generate_random_matrix():
      a = np.random.randint(1, 6, size=(3,3))
      print(a)
