How do I break an array into individual element without using loops

x=[3,4,5,6,7,8,9,10]
for i=1:length(x)
y=x(i)
end
I want a function to give me this result without using a loop

Repetition doesn't answer the question. The example you gave is ostensibly the thing you want, but in that example, y is a scalar which changes value with each loop iteration. So if there is no loop, what is the equivalent? I posed two interpretations:
- A single scalar variable which is multivalued (which is nonsense)
- A pile of numbered scalar variables (which are not practically addressable)
If we assume that you mean to create a pile of numbered variables, then there's another question you need to answer. Once you have a hundred numbered variables in memory, how do you intend on addressing them? Spoiler: the solution to the unnecessary problem you're creating is another problem.
As to how you'd create them all those variables, well that would still involve a loop. If you don't want a loop, then you're going to have to write it all out like @Image Analyst pointed out. At that point, if you just intend on writing out every single operation on every single element of every array in your entire workflow, then what's the point in using MATLAB to do it?

y = reshape(x, 1, 1, [])
y(:, :, 1)
This makes it a 3 D array
If you want it as a cell array then
y = num2cell(x)
celldisp(y)
The loop you use is just looping through x vector.

Perhaps you mean’t:
fprintf('y = %d\n', x(:))
Just for printing values as you do using loop.
