Is the following sample mean and variance fully vectorised?

I wish to calculate the sample mean and the variance. The following is an attempt:
mu=sum(X)/m;
sigma2=sum((X-mu).^2)/m;
mu=mu.';
sigma2=sigma2.';
Is the above fully vectorised as I haven't used any loops (I'm new to this sort of vectorised implementation, so I'm not sure if this code above is fully vectorised or not)?
Any help is highly appreciated.

The best what you can is you can compare the speed with your code and Matlab’s inbuilt function using tic toc . Looks to me that your code is already vectorised.
