How to have variables displayed in workspace after every while loop iteration?

Hi all,
I have a while loop in which my variables are only stored in the workspace after the entire loop is completed. Is there any way that I can store the variable in the workspace after each iteration of the loop, because I need to use these values while the loop is still running. Thank you!

Regarding "additional questions" &nbsp Your chance to get a good answer increases if you make it a separate question with an appropriate subject line.
out(end+1) = str2num(value); &nbsp might work.

The easiest way (without seeing your code) is to initialise a counter before the loop, increment it within the loop, and subscript the variables calculated in the loop:
k1 = 1;
while some_condition
a(k1) = some_expression;
b(k1) = some_other_expression + a(k1);
k1 = k1+1;
end
Here, ‘a’ and ‘b’ will be available as vectors at the end of the loop, and available to each other within the loop. That’s as specific as I can get.

Not sure if you are having issues with the worksplace, or if you are actually trying to say you are having trouble displaying values to the screen while running the program
Instead of using
out(length(out) + 1) = str2num(value)
Can you use...?
out(i) = str2num(value)
Then, can you use...?
disp(out(i))
Or if you want to keep track of which iteration you are on also,
disp(['Iteration ',i,'- Out value of ',out(i)])

Thank you for your help, but my question is that out is not being displayed in the workspace as the loop is running because I want to be able to access the variable while the loop is still running in another code that will be running in parallel. Also if you dont mind can you please take a look at my other question above^. Thank you!
