Thanks. Would you mind pointing me in the direction of any documentation 
on that particular method, please? I presume that the (10,10,10,10) 
refers to the dimensions of the dimensions of the new array (the first 
three 10s) and the step size to iterate (the last 10) but I am not sure 
about the mean(3).
