Ruby 矩阵 eigen()函数
eigen() 是Ruby中一个内置的方法,用于返回矩阵的Eigensystem。
语法 :mat1.eigen()
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 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]]
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:
