Error in ==> portland at 6
m = size(graph,2);

I m beginner with matlab and going to start research work... plz help me out how can I solve this error...

[Guillaume]

You've accepted your own answer. I assume that you've solved the problem, then?

[Kratika Jaiswal]

sorry, I didn't solve... help me out...

There should be more to the error message (for example, the call to plotrand). Please post the whole error message.

In any case, the error is very clear. The variable graph does not exist. You'll have to make sure it exists somehow. Possibly, it is an input to plotrand which you didn't pass.

Without seeing the code of plotrand or the code that calls it, it is impossible to say more.
