Please explain the output
Make a MATLAB function that: 1. Takes in two different numerical inputs (A & B), inputs will be any integer from 1 to 5000 2. The larger number between the two inputs will be halved, while the lesser one will retain 3. The previous step reiterates until both new values will be less than 1. 4. The output will be the number of iterations it took to get both values less than 1 For example: Inputs: 7 & 3 (7,3) --> (3.5, 3) --> (1.75, 3) -> (1.75, 1.5) --> (0.875, 0.75) Output: 5 The output is 4 because it took such a number of iterations for both values to be less than 1. Other Test Cases: INPUT A INPUT B 1 1 7 8 3 10 OUTPUT 2 5 8
