Finding standard deviation/ error distribution of 3D points

Hi, I'm kind of new to MATLAB. I am trying to find the error distribution (standard deviation) of a 3D point data set. I have the following situation:

 One central point (can consider as mean) and points (trials) all around it. Kind of like a darts board. How can I find the error distribution of the points around this center using a 3D set

i.e. center [2,4,5] and points [2,5,6];[2,4,3]........

Thanks in advance!

Use matlab's 'mean' and 'std' functions. See their documentations.
