Add new double array within cell for each iteration in a for loop

I'm trying to get many values out of an excel sheet.

Is it possible to have a cell variable which gets added one more array of double values for each iteration, and how do i write it?

Outside a for loop i can write:

hourValues{1} = some code;
hourValues{2} = some code;
hourValues{3} = some code;

and i will get a 1x3 cell named hourValues which with some code will contain my 3 arrays of double. But how to write this inside a for loop?

hourValues=cell(1,3);
for i=1:3

    hourValues{i} = some code;
    
end

Thanks for reply. Then i guess my problem is in the way i use String. For some reason i don't get any error.

When the code:

hourValues{1} = some code(raw(:,3),['1']);
hourValues{2} = some code(raw(:,3),['2']);
hourValues{3} = some code(raw(:,3),['3']);

is written like that (outside any for loop) i get:

But when writing inside a for like this:

for i=1:3
text = string(i);
hourValues{i} = some code(raw(:,3),[text]);
end

i just get this:

How should i pass the string to get it to work?

(Or could the problem be elsewhere?)

text = num2str(i)

There is something weird with the code i use. No matter how i pass the string it doesn't work, so i will have to open a separate question on that. You've answered my questions Matt J, thank you. :)

string() works by the way, and strangely num2str gave me char. Example, this code:

a = 1;
b = string(a);
c = num2str(a);

returns this:
