Python中的 numpy.diagflat()

numpy.diagflat(a, k = 0):创建一个二维数组,其中 array_like 输入作为新输出数组的对角线。

参数 :

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.

返回:

array with the array_like input as a diagonal to the new output array.
Python
# Python Program illustrating
# numpy.diagflat method
 
import numpy as geek
 
print("diagflat use on main diagonal : \n", geek.diagflat([1, 7]), "\n")
 
print("diagflat use on main diagonal : \n", geek.diagflat([1, 7, 6]), "\n")
 
# Diagonal above main diagonal
print("diagflat above main diagonal : \n", geek.diagflat([1, 7, 6], 1), "\n")


输出 :

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]]
