How to add an entry to a vector after each iteration of a loop?

I want to calculate a number inside a loop n times and append each calculation to a row vector each time. How can I do this?

One possibility:

n = 10;
for k1 = 1:n
    number(k1) = exp(k1/10);
end

You will have to define what ‘calculate a number’ means, and code it appropriately. (I did a random calculation here to illustrate the approach.) The ‘number’ vector in this syntax is a row vector (the MATLAB default), so it satisfies your requirement.

Sorry for being so vague. I don't know how many iterations the loop needed to run until the loop is done running. Each iteration of the loop I calculate an error and I want to be able to store each individual error from each loop iteration in a vector.

Without more information I cannot provide specific code or even a relevant example.

However it would be most appropriate for you to use a while loop. See for an example Implementing a while loop into my code? for a way to do this correctly. You will of course have to make appropriate changes in your code to do the calculation you want, but this example illustrates the appropriate syntax.
