MATLAB: How to delete two minimum elements in a vector

Question

wonder how to delete two minimum elements in the vector and then calculate the mean value of new vector

the vector is like A=[ 70, 56 , 30, 10 , 83 , 78, 77, 90]

code should be flexibe enough to calculate for any vectors

Answer 1

EDITED

n=2; % two smallest values
u=unique(A);
if numel(u)==1 || numel(u)==2
Result=[] 
else
Result=mean(A(~ismember(A,u(1:n))))
end
