I run the following command to genrate two variables joint normally distributed with mean Mu and covariance matrix Sigma, which are defined below
MU=zeros(2,1)
sigma=[1 0.7;0.7 1]
M=mvnrnd(MU,sigma,N)
Then it genartes N,2 vector. But I want to know what the two columns represent.
Thank you!

The two columns represent the two variables measured for each case, and the N rows represent the N randomly selected cases from this bivariate normal distribution. For example, the cases/rows might be analogous to people, and the variables/columns analogous to their heights and weights.

Sorry, I don't see what's going on with that.
You'd better open a new question.
