 % Example: 3x2 array
 myArray = [-1,-2;-3,2;-3,-4]; 
 % Make all values in array positive
  myArray = abs(myArray);
% Mean value of array
m = mean(myArray) % m returns a row vector where each column is the mean of each column of your array
% If you want a single mean value for all values of your array
% concatenate values in a single row
array = [myArray(:,1); myArray(:,2)];
m_all = mean(array);
