[SciPy-user] Cov of 2 vectors

[sandeep.prasad at tcs.com]

Dear All,

How do i compute the covar of 2 vectors. The cov module in scipy always 
returns a 2 by 2matrix even if the vectors are of len >2 , how is this 
possible??

However for the covariance of x and y i need a single number, are there 
any built in functions for this??
