Sort an array logical like a stair

Hello everyone,
I got a simple problem and I thought maybe there is already a function in MATLAB I could use. I got an array like in the picture and I want to sort the values like the route from the red line.
At the end I want a 1xN array.
Do somebody know how to sort them easily like this ?
Thanks!

There are 3 red lines, therefore it is not uniquely clear, what you want as output. Is it wanted, that on the right middle part, the 0.6286 is not included, but the NaN above is?

If you have Image Proc TBX, you can use
watershed
regionprops
on the logical array

No, just don't quite understand how you can get a stair boundaries in general, and why there is no branch. So I give you a generic tool that handle all situations.

" In my array you can see the following path (at least a human)"
But we need an algorithm, if you want this written in any kind of code.

"This is how:"
Good luck for you to find someone who can solve your human problem.
