mu =
30.2800 468.9000 5.0000 0.2042
>> cov=[21 10 40 12]
cov =
21 10 40 12
>> l=lhsnorm(mu,cov,10)
Index in position 1 exceeds array bounds (must not exceed 1).
Error in lhsnorm (line 59)
x(:,i) = norminv(x(:,i),mu(i), sqrt(sigma(i,i)));
why is it showing this error and how can i eliminate this error?
thanks in advance

When your mu is a vector of length 4, then your cov must be a 4 x 4 positive definite (covariance) matrix, not a row vector.
