# Python Programming Illustrative
# NumPy. trio method

 

import numpy as geek

 
# input line

a = geek.matrix ([[ 1 , 21 , 30 ], 

[ 63 , 434 , 3 ], 

[ 54 , 54 , 56 ]])

 

print ( "Main Diagonal elements:" , geek. triu (a), "" )

 

print ( " Diagonal above main Diagonal elements: " , geek. triu (a, 1 ) , "" )

 

print ( "Main Diagonal elements:" , geek. triu (a, - 1 ))

Exit :

 Main Diagonal elements: [[1 21 30] [0 434 3] [0 0 56]] Diagonal above main Diagonal elements: [[0 21 30] [0 0 3] [0 0 0]] Main Diagonal elements: [[1 21 30] [63 434 3] [0 54 56]]
