红宝石 |矩阵特征系统()函数
eigensystem()是 Ruby 中的一个内置方法,它返回矩阵的特征系统。
Syntax: mat1.eigensystem()
Parameters: The function does not accepts any parameter.
Return Value: It returns the Eigensystem of the matrix.
示例 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]]
示例 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:
