I am having this problem as well. To be slightly more precise, here is some example code that generates an error in Matlab 2017a:
tmp = graphshortestpath(sparse(rand(2)),1,[1;2])
The returned error is:
Error using graphshortestpath (line 96)
Invalid destination node.
This code worked for me in Matlab 2016a. Is anyone aware of a workaround in Matlab 2017a?
