I want to loop an exponential until it reaches a certain number and then check how many interations it takes for the loop to reach that certain number

For example loop 2^x until it reaches 4 and then calculate how many times it looped.

Hi @Vincent Kollberg Leeiner,

You can use the “while” function in MATLAB which iterates through a code until a condition is met.

Kindly follow the code below to get the desired results:

% Define the target number 
targetNumber = 4; 
 
% Initialize variables 
x = 0;  
counter = 0;  
 
% Loop until the result reaches or exceeds the target number 
while 2^x <= targetNumber 
    x = x + 1; 
    counter = counter + 1;  
end 
fprintf('It takes %d iterations for 2^x to reach %d.\n', counter, targetNumber); 

Hope this helps!
