Use a for loop inside a vector

The first part was to make a rectangle vector and the second part is to make a curve vector that uses the data from the recktangle and adds a signal with the maximum amplitude noise. I got the first part down, so, I'm trying to get a vector with a for loop inside of it. What I have for now:
curve= [];
for i=1:numel(recktangle)
recktangle(i) = recktangle(i) + (rand() * noise);
end
curve= curve(:);
but it says that curve seems to be unused. How do I nest a for loop in an array?

First vector has a random number of zeros the second has a random number of ones. These two steps should be repeated N times and then linked together in a new rectangle vector.
Curve vector is a rectangle vector+ a random signal with max. amplitude noise.

...First vector has a random number of zeros the second has a random number of ones...
what are the sizes? Please be specific and give a complete explanation. It's always better to create a sample input and expected output.
as far as your explanation on curve vector goes, my answer does exactly that.

I'm not sure what you want, but probably something like this (no need for loop, just one line like below),
curve = recktangle+(rand(size(recktangle))*noise);
