红宝石 |矩阵特征（）函数

eigen()是 Ruby 中的一个内置方法，它返回矩阵的特征系统。

Syntax: mat1.eigen()

Parameters: The function does not accepts any parameter.

Return Value: It returns the Eigensystem of the matrix.

示例 1 ：

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

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]]

示例 2 ：

# Ruby program for eigen() 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.eigen()

输出：
