numpy.diagflat() in Python

numpy.diagflat (a, k = 0): Create a two-dimensional array with the array_like input as a diagonal to the new output array.

Parameters : 

a : array_like input data with diagonal elements
strong>k : [int, optional, 0 by default]
 Diagonal we require; k>0 means diagonal above main diagonal or vice versa.

Returns :  

array with the array_like input as a diagonal to the new output array.

Output : 

diagflat use on main diagonal : 
 [[1 0]
 [0 7]] 

diagflat use on main diagonal : 
 [[1 0 0]
 [0 7 0]
 [0 0 6]] 

diagflat above main diagonal : 
 [[0 1 0 0]
 [0 0 7 0]
 [0 0 0 6]
 [0 0 0 0]]
