n=5; p=4;
u=randn(n, p);
X= sqrt(1-r*r)*u + r*u;
e=normrnd(0*eye(n),5*(n))
beta0=[4;3;2.3;1];
y=X*beta0*(eye(n))'+e;

The code won't run because the value of r is not defined.

change your last line from
y=X*beta0*(eye(n))'+e;
to
diag(X*beta0)+e
I assumed
r=1
the command diag does what you tried with eye(n).
