WebDescription. 1i returns the basic imaginary unit. i is equivalent to sqrt (-1). You can use i to enter complex numbers. You also can use the character j as the imaginary unit. To create a complex number without using i and j , use the complex function. z = a + bi returns a complex numerical constant, z. z = x + 1i*y returns a complex array, z.
