yp = irsa_dft (fxp, fyp, xp, [lm])

Compute Inverse Discrete Fourier Transformations of spectra [fxp,fyp] using yp(t) = (1/N) * sum_(k=1)^N fyp[k] * exp(2*pi*I*fxp[k]*t) for every t in xp

Input:

fxp : Columnvector – frequency points

fyp : Matrix with the spectrum values in its columns

xp : Vector – sampling points for the resulting timeseries

lm : Boolean – use lesser memory if 'true' (slower). Default is 'false'.

Output:

yp : Matrix with values of the IDFTs in its columns
