# Generate data with a particular correlation matrix

# A useful fact is that if you have a random vector x with covariance matrix Σ, 
# then the random vector Ax has mean AE(x) and covariance matrix Ω=AΣA^T. 
# So, if you start with data that has mean zero, multiplying by A will not 
# change that.
