I want to generate multiple (say 1000) random samples from the normal distribution each of size 200. How do I achieve that. Thanks!

rnv=randn(200,1000); % generate 1000 column samples of 200
Refer to the subsample sets as rnv(:,idx) where idx is the desired sample number. Don't even think of trying to build named variables for this.

One way to go about this:
x = randn(200,1000);
This generates normally distributed pseudo-random numbers between 0 and 1.
