Not having my first "FOR LOOP" numbers assigned inside my MATLAB code

Hi all,

I was wondering if anyone could assist me with a silly question on MATLAB! The story is that I'm generating some numbers in my code, catgorized into two separate ranges. Now, I need to implement those numbers in the other part of my code, as follows:

xs = strings(1,24);

for i= 1:24
    if x(i)==1
        xs(i)  = "Set WinS_Construct = R1WinConstruction";
    elseif x(i)==2
        xs(i)  = "Set WinS_Construct = R2WinConstruction";
    elseif x(i)==3
        xs(i)  = "Set WinS_Construct = R3WinConstruction";
    elseif x(i)==4
        xs(i)  = "Set WinS_Construct = R4WinConstruction";
    end
end

xs = strings(25,29);

for i= 25:29
    if x(i)==13
        xs(i)  = "13";
    elseif x(i)==14
        xs(i)  = "14";
    elseif x(i)==15
        xs(i)  = "15";
    elseif x(i)==16
        xs(i)  = "16";
    elseif x(i)==17
        xs(i)  = "17";
    elseif x(i)==18
        xs(i)  = "18";
    end
end

While I could sucessfully generate the "x" numbers, I'm not sure why MATLAB does not generate any number for my first loop. To calrify more, my "xs" strings includes only numbers for i=25:29- and I'm missing "xs" strings for i=1:24!

Any help would be greatly appreciated!

Thanks!

xs = strings(25,29);

That line of code requests that all of xs be overwritten with a 25 by 29 array of string objects.

Remove that line and change

xs = strings(1,24);

to

xs = strings(1,29);
