% Function to add all current column with current row, creating an output matrice of the same dimensions, containing the sums.% Example:% Input: A = [1 2 3; 4 5 6]% B(1,1) = 1+2+3(row) + 1+4(column) = 11% Output: B = [11, 13, 15; 20, 22, 24]function B = matsum(A)K=size(A);B = [];for c=1:K(2) % Loop through columns for d=1:K(1) % Loop through rows SumC = 0; SumR = 0; for e=1:K(2) % Add all data in current column SumC = SumC+A(e,d); end for f=1:K(1) % Add all data in current row SumR = SumR+A(c,f); end B(d,c) = SumC+SumR; endend
