I want to run a loop until a value is reached and, then, I want to use that reached value to continue the loop

Hi everyone! Thanks for helping.
I'm running a code about hydrogeology. I'm calculating tha saturated portion of a soil depending on rainfall amount.
I need Matlab to calculate this saturated thickness until a certain value H is reached. This value is the maximum depth of the soil of course.
When the loop reaches H, I want Matlab to keep on doing the calculations assuming H as the new starting point, instead of the value > H that it has been encountered.
How can I do this? Thanks for helping!

Hard to say for sure, but maybe some structure like this (but with a break condition - which was unspecified in the question):
H = 100;
thickness = 0;
while true
thickness = thickness+1;
if thickness >= H
thickness = thickness-H;
end
end

Many many thanks!! Finally I managed by doing this:
ii = 1;
m(1) = m0;
deltam(1) = 0;
output(1) = 0;
while true
ii = ii + 1
output(ii) = prod*m(ii-1);
deltam(ii) = ((input(ii)-output(ii))./den2(ii));
m(ii) = (m(ii-1) + deltam(ii));
if m(ii) >= H;
m(ii) = H;
end
end

Finally I just added an if loop inside the code I posted earlier:
if ii > a (a was the length of my dataset)
break
end
And so it runs normally now :D
