Solución detallada
Tenemos la ecuación:
$$z = \operatorname{atan}{\left(x^{2} + y \right)} + \frac{1}{x y^{2}}$$
cambiamos:
$$z = \operatorname{atan}{\left(x^{2} + y \right)} + \frac{1}{x y^{2}}$$
Abrimos los paréntesis en el miembro derecho de la ecuación
z = 1/x*y+1/2 + atany+x+2
Sumamos los términos semejantes en el miembro derecho de la ecuación:
z = 1/(x*y^2) + atan(y + x^2)
Obtenemos la respuesta: z = 1/(x*y^2) + atan(y + x^2)

$$z_{1} = i \left(\operatorname{im}{\left(\frac{1}{x y^{2}}\right)} + \operatorname{im}{\left(\operatorname{atan}{\left(x^{2} + y \right)}\right)}\right) + \operatorname{re}{\left(\frac{1}{x y^{2}}\right)} + \operatorname{re}{\left(\operatorname{atan}{\left(x^{2} + y \right)}\right)}$$
z1 = i*(im(1/(x*y^2)) + im(atan(x^2 + y))) + re(1/(x*y^2)) + re(atan(x^2 + y))
