Ran in:
a = 8
a = 8
b = a*1i % method 1
b = 0.0000 + 8.0000i
c = complex(0, a) % method 2
c = 0.0000 + 8.0000i

+1 of course, as this seems to cover the bases completely.
I would only add that MATLAB does not have a purely imaginary form, only a complex form. Since the OP seems to be hoping to see a number of the form 8i, they may become confused when seeing a zero real part displayed. If the real part is zero, then the result is purely imaginary.
