MATLAB: Loop with different outcome name

for looploop

Hi,
I'm trying to create a loop that gives me outcomes with different names
For example,
for x=1:3
y=x+2
end
This code gives me y=3, y=4, y=5
But I want to change my code so that it gives me something like
y1=3, y2=4, y3=5
so that I would be able to know which y corresponds to which x values later.
Is there anyway to acheive this?
Many thanks in advance!

Creating variable names like y1, y2, ... is not a good coding practice and highly non-recommended: https://www.mathworks.com/matlabcentral/answers/304528-tutorial-why-variables-should-not-be-named-dynamically-eval. A better approach is to use array
y = zeros(1, 3)
for x = 1:3
    y(i) = x+2
end
Then access values using indexing
y(1) % access first element

Also, note that your for-loop can be vectorized
x = 1:3;
y = x+2;
