Why not read the MATLAB help? You can do this easily from MATLAB itself:
doc mean
Or by using your favorite internet search engine (it takes just 0.1 seconds).
The MATLAB documentation for mean states that " M = mean(A,dim) returns the mean along dimension dim ".
So your code finds the mean along the third dimension.

@KSSV: What is the "mean(k,3) gives mean of a 3D matrix" actually?
Is it the mean of all elements, the mean of some elements, the mean along a particular dimension? Which of those are you trying to explain? (it is one of them, but which one?)
