convolve2D {waveslim} | R Documentation |
Use the Fast Fourier Transform to perform convolutions between a sequence and each column of a matrix.
convolve2D(x, y, conj = TRUE, type = c("circular", "open"))
x |
M{\times}N matrix. |
y |
numeric sequence of length N. |
conj |
logical; if TRUE , take the complex conjugate
before back-transforming (default, and used for usual convolution). |
type |
character; one of "circular" , "open"
(beginning of word is ok). For circular , the two sequences
are treated as circular, i.e., periodic.
For |
This is a corrupted version of convolve
made by replacing
fft
with mvfft
in a few places. It would be nice to
submit this to the R Developers for inclusion.
