Of course it's not running

vg= (0 -1 -2 -3 -4 -5 )

is not valid syntax. Perhaps you meant:

vg = [0 -1 -2 -3 -4 -5]

which could be simply written

vg = 0:-1:-5

Then,

Id= Go*(((q*ND*t^2)/6*es)-(phi-vg)*(1-0.667*((2*es*(phi-vg))/(q*ND*t^2))^0.5);

is missing a closing parentheses somewhere.

The error messages that matlab is giving you do tell you what is wrong.
