How do you determine which numbers in a vector are factors of 144 by indexing through it using loops?

1 visualizzazione (ultimi 30 giorni)
I have a vector of random integer from 1 to 100 with the amount of elements that a user inputs. All operations must be performed using loops, not built-in functions or array operations.
elements = input('Enter how many elements are in the vector: ');
vector = randi([1,100],1,elements)
How do I determine how many numbers in the vector are factors of 144 and what those number are?

tf = false(size(vector));
for i = 1:length(vector)
if mod(144,vector(i)) == 0
tf(i) = true;
factors = vector(tf);
Or instead of mod(), you could do
if 144./double(vector(i)) == round(144./double(vector(i)))
