Assume X; Y and Z are jointly Gaussian mean-zero random variables with the (joint) variance given by K := Var(X; Y;Z) =[2 1 0;1 2 1;0 1 2 ]

Assume X; Y and Z are jointly Gaussian mean-zero random variables with the (joint) variance given
by
K := Var(X; Y;Z) =[2 1 0;1 2 1;0 1 2 ]

(a) Determine the distribution of U = X + Y + Z.
(b)Let W = X + Y and V = X + Y . Compute the joint distribution of W and V .
after assiging the values to k matrix how can i find u

This doesn't look like a question about MATLAB, so you may have better luck 
posting it to a different newsgroup, like sci.stat.math (which you can 
access via Google Groups if your news server doesn't carry it.)

Of course, you'll probably have much better luck over there if you post what 
you've tried to solve this homework problem first, not just the homework 
question.
