语法：mat1.eigensystem()

参数：该函数不接受任何参数。

返回值 ：它返回矩阵的Eigensystem。

例子 1 :

# Ruby program for eigensystem() method in Matrix
  
# Include matrix 
require "matrix"
  
# Initialize a matrix 
mat1 = Matrix[[1, 0], [0, 2]]       
  
# prints the eigensystem
puts  mat1.eigensystem()

输出:

Matrix[[1.0, 0.0], [0.0, 1.0]]
Matrix[[1.0, 0], [0, 2.0]]
Matrix[[1.0, 0.0], [0.0, 1.0]]

例2 :

# Ruby program for eigensystem() method in Matrix
  
# Include matrix 
require "matrix"
  
# Initialize a matrix 
mat1 =  Matrix[[1, 1, 5], [4, 1, 5], [11, 2, 12]]        
  
# prints the eigensystem
puts  mat1.eigensystem()

输出:
