I had a perfectly-functioning program that used this line:
c = randi([1,n],mn,1)
where n and mn are integers. I've re-opened the program to do a monte carlo simulation, and all I get is an error message stating:
Error using randi
Too many input arguments.
Mind you, I haven't changed a coma in the program. I'm just running it again to re-acquaint myself with had I had done.
