iffteqeng

Perform inverse FFT in an engineering way

function [time output] = IFFTEQENG(data,dt,L) calculates the ifft of vector "data" (in frequency domain), which resulted from fft of input (in time domain) of length "L" and time step "dt". "time" and "output" are self-expained. Attention should be paid as "time" vector corresponds to maximum of length(data)*dt points, which normally should not be equal to the initial time vector (as fft sould have been performed in NFFT>length(input_time) points)
