MATLAB has strict format requirement.
1. A and B are in double format. C is in cell format. (C is read by: [~,C,~] = xlsread('C:\XXX\XXX.xlsx','Sheet1','M2:X2')
A =
[10
15
20
25
30];
B = [1423992 1356920 1356920
440353 436518 436518
1325369 1307792 1307792
1485221 1165422 1162373
1496009 1489431 1489431
6170946 5756085 5753036
];
C ='SECTOR' 'MKVALM' 'DVYDC' 'DVYLD500'
How can I combine A, B and C to get a matrix D so that:
D =
SECTOR MKVALM DVYDC DVYLD500
10 1423992 1356920 1356920
15 440353 436518 436518
20 1325369 1307792 1307792
25 1485221 1165422 1162373
30 1496009 1489431 1489431
SUM 6170946 5756085 5753036
Notice that the D(7,1) = 'SUM'.
2. Once I get D, I want to add an empty row and a row with numbers to get E,
E = SECTOR MKVALM DVYDC DVYLD500
10 1423992 1356920 1356920
15 440353 436518 436518
20 1325369 1307792 1307792
25 1485221 1165422 1162373
30 1496009 1489431 1489431
SUM 6170946 5756085 5753036
35 12 12 14
Notice there is an empty row between 'SUM 6170946 5756085 5753036' and '35 12 12 14'.
Any help will be appreciated!

You cannot construct that D vector except as a character array, in which case D(7,1) would be 'S' .
If you construct D as a cell array, you would have to show quotation marks and [] in the display of it:
'SECTOR' 'MKVALM' 'DVYDC' DVYLD500'
[10] [1423992] [1356920] [1356920]
and so on.

You are absolutely right. In this situation I guess I have to use cell array.

Ac = num2cell(A);
Bc = num2cell(B);
D = [C;Ac,Bc(1:end-1,:);{'SUM'},Bc(end,:)];
E = [D;cell(1,4);{35, 12, 12, 14}];
