IFFT function in R? -


in matlab, there ifft function (inverse fast fourier transform) - details.

in particular, following:

ifft(x,n,dim)

which returns inverse dft of x across dimension dim.

in r, there similar function apart of signal package - details

however allows x input array, follows:

ifft(x)

question:

is there way include dimension, such dim in matlab function, r?

thank taking @ question, helpful.

are looking ? mvfft (with inverse = true)?

mvfft (inverse) fft columns, can reshape data:

  • t matrix transpose
  • aperm array extension of t (dimension permutation)
  • you can reshape array matrix dim<-
    (package arrayhelpers has convenience functions such conversion of array matrix , back).
