Accepted Answer. They're not meant to be empty. Going up we see, [V,I] = min ( [Va,Vd], [],2); It's the colum index where a minimum is found. I don't know what Va and Vd are. if they are column vectors then [Va, Vd] only has two columns, and obviously, you're never going to find a minimum in the 3rd column.. Don franklin chevy bardstown
