If I have the matrix as next: /// F = [ 3 4 5 6 2 2; 4 5 2 6 6;8 4 3 6 7 ; 5 6 3 8 5 ] /// /// I like to make the summation of rows, then columns in matrix separately and put the result in the new matrix. the number elements in new matrix supposed to be 9. as next:/// Sum = [ 20 ,19,13,26,20,20,23,28,27 ]/// Then make a graph to represent this values, as the relation between X , Y. /// Thank you

This works:
F = [ 3 4 5 6 2 ; 4 5 2 6 6; 8 4 3 6 7 ; 5 6 3 8 5 ];
Fc = sum(F,2);
Fr = sum(F);
Sum = [Fr Fc']
Sum =
20 19 13 26 20 20 23 28 27
Note — Row 1 of ‘F’ has an extra 2. The version here is correct., and gives the correct result.
