Python中怎样实现奇异值SVD分解

 1 >>> from numpy import *;
 2 >>> U,Sigma,VT=linalg.svd([[1,1],[]7,7])
 3 SyntaxError: invalid syntax
 4 >>> U,Sigma,VT=linalg.svd([[1,1],[7,7]])
 5 >>> U
 6 array([[-0.14142136, -0.98994949],
 7        [-0.98994949,  0.14142136]])
 8 >>> Sigma
 9 array([ 10.,   0.])
10 >>> VT
11 array([[-0.70710678, -0.70710678],
12        [-0.70710678,  0.70710678]])
13 >>> 

 主要是两条语句：

from numpy import *;

U,Sigma,VT=linalg.svd([[1,1],[7,7]]);
