Python中怎样实现奇异值SVD分解

>>> from numpy import *;
>>> U,Sigma,VT=linalg.svd([[1,1],[]7,7])
SyntaxError: invalid syntax
>>> U,Sigma,VT=linalg.svd([[1,1],[7,7]])
>>> U
array([[-0.14142136, -0.98994949],
       [-0.98994949,  0.14142136]])
>>> Sigma
array([ 10.,   0.])
>>> VT
array([[-0.70710678, -0.70710678],
       [-0.70710678,  0.70710678]])
>>> 

 主要是两条语句：

from numpy import *;

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