Sum across columns for each row

I have a 296x6 matrix called impactScore, and the maximum value (max1, max2 . . . max6) from each column(call them col1,col2 . . . col6).

For Row 1, i want to find

(row 1 col 2) - max1)^2

(row 1 col 2 - max2)^2

Repeat this for all 6 columns and sum this value

Repear this calculation for each row

Essentially

where i represents each row and j represents each column.

Assuming yor question as

" (row 1 col 1) - max1)^2

(row 1 col 2 - max2)^2

(row 1 col 3) - max3)^2

(row 1 col 4) - max4)^2

(row 1 col 5) - max5)^2

(row 1 col 6 - max6)^2 "

Correct me if i am wrong

max_vals = max(impactScore);     % maximum values of each colum(1 to 6)
D = zeros(size(impactScore,1), 1);    % initialize 
for ii =1: size(impactScore, 1)
    D(ii, :) =  sqrt(sum([impactScore(ii,:)-max_val].^2));
end
D % column matrix after calculation

It worked, just had to change max_val in line 4 to max_vals . Thanks!
