numpy.triu(a, k = 0) : Returns copy of array with upper part of the triangle w.r.t k
Parameters :
a : input array
k : [int, optional, 0 by default]
Diagonal we require; k>0 means diagonal above main diagonal or vice versa.
Returns :
Upper triangle of a, having same shape and data-type as a.
# Python Programming illustrating # numpy. triu method import numpy as geek # string input a = geek.matrix([[1, 21, 30], [63 ,434, 3], [54, 54, 56]]) print("Main Diagonal elements : \n", geek. triu(a), "\n") print("Diagonal above main Diagonal elements : \n", geek. triu(a, 1), "\n\n") print("Main Diagonal elements : \n", geek. triu(a, -1)) |
Output :
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]]
