How can I make a connection between these points? Like this:

I have tried 

se = strel('line', LEN, DEG);

But nothing is changed.

Please help me

Thank you

You can use roipoly to create a mask defined by the points.
Given a binary mask you can use bwmorph(BW,'remove'); to get the boundary and you are done.

The only problem is determining the order of the points, different order defines different mask. This one you'll have to figure for yourself.

Example of ambiguity in ordering the points:
