Deconvolution (polynomial division) in R

Question

I need to perform a deconvolution of two vectors. This is equivalent to polynomial division. For example, in Matlab I would use deconv function. Is there a similar/equivalent function in R?

Answer 1

There is deconv in package pracma

c = c(10, 40, 100, 160, 170, 120)
u = c(1, 2, 3, 4)

#install.packages("pracma")
library(pracma)
deconv(c, u)
#$q
#[1] 10 20 30

#$r
#[1] 0 0 0
