$DFTallField
 ifoutput
 Intype    fi    ff    N          // ifoutput, Intype, and N are integers, the others are floating points.

This function allows the program to calculate the field of certain frequencies by discrete Fourier transform (DFT).

ifoutput: 1 means the program outputs the DFT results at output-step. 0 means it outputs results only after time-step.
Intype: 1 means fi and ff are frequencies; on the other hand, 2 means they are wavelengths.
fi: initial frequency or wavelength.
ff: final frequency or wavelength.
N: the number of frequencies or wavelengths you want to calculate between fi and ff.

Example

 2    400e-9    400e-9    1
