I have a problem about the integration of a function. The maple returns mathematical form of the given command

the function is

fn :=(-4.079067798*10^(-16)+3.422708023*10^(-16)*I)*(3.363377947*10^(-11)+5.977507284*10^(-12038)*I+(3.363377947*10^(-11)+4.678081798*10^(-22)*I)*erf(1.664331698*10^15*qq-0.2503507367e-1-4.649313602*I)) *exp(-2.77*(qq/(tau*tau))^2)*exp(-I*w0*qq)*exp(-(ss-qq)/T_pop)

qq is the integration variable qq=-inf..ss

w0=10^15

tau=10^(-15)

T_pop=30e-15

how to plot exp(f)*erf(g) where f and g are complex function

(-6.328281880*10^(-49)-1.071713312*10^(-47)*I)*exp(-5996.664400+2.000000000*10^14*del+(1.547600000*10^16*I)*del)*(erf(11.+77.38000000*I+1.000000000*10^14*del)-1.*erf(-4.+77.38000000*I+1.000000000*10^14*del))

del from -100e-15 to 100e-15

I want to make a nested loop and store the data(with complex numbers) in matrix in order to make 3D plot.
