How to stop a loop when the variable approaches infinity?

I am new to MATLAB. I have to evaluate two variables i.e. X and U. I need to write an if loop (or while loop) in a script where X takes a value and does calculations on a set of equations to calculate U. The loop should stop when U approaches infinity. How can I code this MATLAB? Thank you.

"The loop should stop when U approaches infinity",

Matlab implementation is all about Maths, you should define it specifically.

data_value=...?? % Define max U value here, any specific (U approaches infinity)
U=...?? Initialize varaible_data
while U<data_value
%% Code 
U=....% Update (Ensure that it is increasing)
end

If you're using a for loop

for k = 1 : 9999999
    X = whatever;
    U = SomeFunction(X);
    if U > 1e8 % Whatever number you think is "approaching infinity".
        % If U is bigger than we want to allow, break out of the loop.
        break;
    end
end
