Q: Error in MatLab function isisomorphic I am checking to see if two colored graphs are isomorphic using the built-in MatLab function isisomorphic.  The program, however, is throwing me an error.  I would like to know if this is a MatLab error or if there is a mistake in my code.  The specific example where isisomorphic fails is reproduced below.  The error is also reproduced below.  The problem is that the code tries to concatenate two objects, compBinSize(bins1) and compBinSize(bins2), but one is 4x1 while the other is 1x4.  Do others get the same error, and if so how do I resolve this?
Note: I am running Windows 7, MatLab R2016b.  
Sample code:
G1 = [0 1 1 1 ; 1 0 0 0 ; 1 0 0 0 ; 1 0 0 0]; 

G2 = [0 1 1 0 ; 1 0 1 0; 1 1 0 0 ; 0 0 0 0];

H1 = graph(G1); 

H2 = graph(G2); 

isisomorphic(H1,H2)

Error in graph/isomorphism>refineNodeCategories (line 178) compSizes = [compBinSize(bins1), compBinSize(bins2)];


A: This is a known issue.  See the following bug report to resolve it:
