Example of how to use transverse wakes and impedances for equivalent computation.
M. Borland, 2018

makeWI
        Makes wake file, then uses sddsfft to transform it into an impedance.
        Output wake file: wake.sdds
        Output impedance file: impedance.sdds

imped1.ele
        Run with impedance
wake1.ele
        Run with wake

Sequence:
% makeWI
% elegant wake1.ele
% elegant imped1.ele
% sddsplot -column=t,yp wake1.out imped1.out -grap=dot,vary
