A=[1 4 5 10 9 3 2 6 8 4]
B=[1 7 3 4 1 10 5 4 7 4]
fRow = B+A(1);
sRow = B+A(2);
tRow = B+A(3);
foRow = B+A(4);
fiRow = B+A(5);
siRow = B+A(6);
seRow = B+A(7);
eRow = B+A(8);
nRow = B+A(9);
teRow = B+A(10);
ans = [fRow; sRow; tRow; foRow; fiRow; siRow; seRow; eRow; nRow; teRow]
please i need help with this, how can i write the code to solve the answer if A and B array length is the diffrent from my own array length
Let say A and B will have to be inputted by the user, and the array Length of A and B inputted by the user is less or greater than 10, how will my code solve that.
This is the output
ans =
2 8 4 5 2 11 6 5 8 5
5 11 7 8 5 14 9 8 11 8
6 12 8 9 6 15 10 9 12 9
11 17 13 14 11 20 15 14 17 14
10 16 12 13 10 19 14 13 16 13
4 10 6 7 4 13 8 7 10 7
3 9 5 6 3 12 7 6 9 6
7 13 9 10 7 16 11 10 13 10
9 15 11 12 9 18 13 12 15 12
5 11 7 8 5 14 9 8 11 8
ans =
12

"but the problem now is the output is not in array form, how can make it array fom?"
What exactly is "array form"?
The answers that DGM has shown you are exactly the same as if you do the same calculation in a loop.
Just much simpler.

Here is an alternative way using the repmat() function to explicitly turn A and B into 2-D matrices before adding them together:
A=[1 4 5 10 9 3 2 6 8 4]
B=[1 7 3 4 1 10 5 4 7 4]
A2 = repmat(A', 1, length(B))
B2 = repmat(B, length(B), 1)
C = A2 + B2;
It gives the same result as your "ans" and can handle any length of A and B, as long as they're the same of course
