Hi , I try to use the matlab to express Xall

X1 = X + S(1,1) 
X2 = X + S(2,1)
X3 = X + S(3,1)
X4 = X + S(4,1)
X5 = X + S(5,1)
X6 = X + S(6,1)
X7 = X + S(7,1)
X8 = X + S(8,1)
X9 = X + S(9,1)
X10 = X + S(10,1)
X11 = X + S(11,1)
X12 = X + S(12,1)
X13 = X + S(13,1)
X14 = X + S(14,1)
X15 = X + S(15,1)
X16 = X + S(16,1)
Xall = [X1;X2;X3;X4;X5;X6;X7;X8;X9;X10;X11;X12;X13;X14;X15;X16];

but I don't know how to use for loop to simplify it

I tried the

for   n = 1:16
X(n) = X + S(n,1)
end

but it says A(:) = B, the number of elements in A and B must be the same.

Why the transpose?

Hi Roberson, It doesn't work.

 In my project, S is 16 by 2 double and I try to create the array of Xall from the first column of S and Yall from the second column of S. For example X1 = X + S(1,1) ...
Yn = Y + S(n,2) where Yall = [Y1;Y2;...Yn]
for y,  For example X1 = X + S(1,1) ...
Yn = Y + S(n,2) where Yall = [Y1;Y2;...Yn]
I didn't know how to create the array with that element in, for my code I just wrote one by one element and it's not gonna work for tons of tons elements.
