2) How can I generate a matrix of 50-by-1 containing numbers with a

predefined mean and variance?

3 Is it possible to predetrmine "the correlation level" of the

variables in the matrix. For example to create a matrix of 50-by-1

with correlation coeffecient of 0.70 (is this possible also if mean

and variance are predefinied)?
