Error message when plotting network graph in 2018a

I'm having a problem creating a simple network graph from a symmetric adjacency matrix.

     A=[0,1,1,0,0;1,0,1,0,0;1,1,0,1,1;0,0,1,0,1;0,0,1,1,0]
     G=graph(A);
     plot(G);

Creating G is not a problem, but the plot command produces the following error message:

Interestingly, I don't have any problems with R2018b--just with R2018a

I am having the same error messages when I try to use the graphplot function in the econometrics toolbox for a dtmc plot. I did not have this issue previously, but now it has come up for no reason. I have not changed anything in my code

If you're getting the exact same error, have you tried checking what the main answer suggests?

Have you written your own function named rng that is shadowing the rng function included in MATLAB? Check with:

which -all rng

That was it. The Multivariate Granger Causality Toolbox (MVGC), was causing the conflict. Restarted Matlab, made sure not to load the package, and all is fine. Thanks!!!

However, I seemed to have another problem when trying to adjust the node font size:

     plot(G,'NodeFontSize',10,'MarkerSize',10);

produces and error message, whereas

     plot(G,'MarkerSize',10);

works just fine. Again, the problem appears in 2018a but not 2018b. The error message this time is the following:

We added a number of new properties to allow users to customize node and edge labels in graph plots in release R2018b. NodeFontSize is one of those new properties.

Thank you!

Couldn’t produce that error in 2018b so try

clear all

at the very beginning and try again

[Paul Fishback]

Yes, all is fine with 2018b, which I run locally on my own machine. The issue is with 2018a, which I access remotely. Using clear all does not resolve the issue.
