convolve2D(x, y, conj = TRUE, type = c("circular", "open"))
TRUE
, take the complex conjugate
before back-transforming (default, and used for usual convolution)."circular"
, "open"
(beginning of word is ok). For circular
, the two sequences
are treated as circular, i.e., periodic. For open
and filter
, the se
convolve
made by replacing
fft
with mvfft
in a few places. It would be nice to
submit this to the R Developers for inclusion.convolve
