numpy.tril(a, k=0) : Returns copy of array with lower 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 :
Lower triangle of a, having same shape and data-type as a.
Output :
Main Diagonal elements :
[[ 1 0 0]
[ 63 434 0]
[ 54 54 56]]
Diagonal above main Diagonal elements :
[[ 1 21 0]
[ 63 434 3]
[ 54 54 56]]
Main Diagonal elements :
[[ 0 0 0]
[63 0 0]
[54 54 0]]
