Error in code by Ken Deeley on "Exploring risk contagion using graph theory and Markov chains"

Hi, am running this code by Ken Deeley on "Exploring risk contagion using graph theory and Markov chains" but am encountering this error "Undefined function or variable 'graph'. Error in RiskContagion (line 105) G = graph(sectorDist, sectors);"!

Please anyone can help? Thank you.

It’s better you contact the author of the code and clarify by the way matlab has an inbuilt function function . Type graph in your command window if nothing shows up , contact MathWorks Support team by clicking the Contact Us button on the top right corner of this page.

That code was written for R2016a and relies upon graph() which was new as of R2015b. You are using an earlier MATLAB.

thanks @Walter. I think it has to do with the version am using which is R2015a.
