MATLAB: Taking mean without max values

mean max

Hello, How would I take the mean value of a matrix and exclude only the one max value?

Thanks

x=[1,2,3;4,5,6;7,8,500];
mean_value=(sum(x(:))-max(x(:)))/(numel(x)-1);

For 1d vectors rather than a matrix, you can exclude the (:) portions.

Yes, your thought is right

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

mean() also accepts the dimension in which you want to operate

x = [1 2 3 4; 5 6 7 8;10 11 13 14;];
row_mean = mean(x, 2);
[~, idx] = max(x, [], 'all', 'linear');
[~, max_col] = ind2sub(size(x), idx)
