Say, I have an array A of size 100 consisting of 0's and 1's. I need to create a smaller array consisting only of the 1's. At start, I don't know the number of 1's in the original array. Basically, I want to create the subset-array element-by-element as I loop over the elements of the original array and checking for 1's.Any help appreciated. Thanks, Preetam

"create the subset-array element-by-element as I loop over the elements "   is that a requirement or a hint?

I’m not quite sure what you want.
Here are two possibilities:
Array = randi([0 1], 1, 100);
OnesArray = Array(Array==1) % Ones Array
ElemArray = find(Array); % Indices Of Ones In ‘Array’
