Increment components of vector till a desired limit

Hello everyone, I need to increment the components of a column vector in the form of A= [1 2 3 4 5] till every component hits 100.
For example, the first iteration should be A = [1 2 3 4 5 2 3 4 5 6] and the third one A = [1 2 3 4 5 2 3 4 5 6 3 4 5 6 7] and so on till each of the originary 4 components gets to 100; so not only the vector components needs to grow in magnitude, but the actual number of vector components need to grow too. I'm pretty sure that this can be done with a while loop but I'm getting stuck on the syntax.
Thanks in advance to everybody.
clear all
clc
A= [1; 2; 3; 4; 5; 6; 7; 8; 9; 10];
while (i) < 100
A= A+1
i= i+1
end

You know in advance how many iterations are needed: The smallest element must be increased until it is 100.
A = [1 2 3 4 5];
Limit = 100;
Iter = Limit - min(A);
Result = A(:) + (0:Iter); % As matrix, Auto-expanding needs >= R2016b
Result = Result(:).'; % As row vector
Alternative:
Result = repmat(A, 1, Iter + 1) + repelem(0:Iter, 1, numel(A));
Or if you want a loop:
nA = numel(A);
Result = zeros(1, nA * (Iter + 1)); % Pre-allocate
index = 0;
for k = 0:Iter
Result(index + 1:index + nA) = A + k;
index = index + nA;
end

Use any():
A= [1; 2; 3; 4; 5; 6; 7; 8; 9; 10];
thisA = A(end-3:end);
maxIterations = 1000; % Set up a failsafe to prevent an infinite loop
loopCounter = 1;
while any(thisA < 100) && loopCounter < maxIterations
thisA = A(end-3:end) + 1;
A = [A; thisA];
loopCounter = loopCounter + 1;
end
A
