mean value of array between values

Hi guys,

I need your help, I need to know a mean value of array between values (without max and min), for example:

a = [1 2 ; 3 4 ; 5 6]

max(A)=6

min(A)=1

Equation: (2 + 3 + 4 + 5)/4

I thought in something like:

( a(i)-max(a)-min(a) )/4

But that's wrong.

Please help me.

Yes, your thought is right

 mean_value_ex = (sum(a(:))-(max(a(:))+min(a(:)))/ (numel(a)-2))
