Maybe

skeleton = bwskel(imclose(yourimage, strel('diamond', 2)))

It was introduced in r2018a. Please upgrade.

You can use

skeleton = bwmorph(imclose(BW, strel('diamond', 2)), 'skel', Inf);

To get similar (but not identical) results to bwskel. bwskel is an improved version and indeed you'll have to upgrade if you want to use it.

Try

binaryImage = imfill(binaryImage, 'holes');
skelImage = bwmorph(binaryImage, 'skel', inf);

Thank you again!

I want to mesure this angles, beween the main spine and Y axe,

and for this I tried to aprox. these spines.

I tried with regionprops -> Orienation too, but I think is not helpful.

Guillaume 2020-2-10

Well, you really need to upgrade!

The bwskel I suggested has an optional input, MinBranchLength which would allow you to trim the skeleton to the main trunk. From then on, the 'Orientation' of regionprops would be a lot more accurate. Unfortunately, bwmorph doesn't have the same option.
