deconv | R Documentation |
Deconvolution and polynomial division.
deconv(b, a)
b , a |
real or complex vectors. |
deconv(b,a)
deconvolves vector a
out of vector b
.
The quotient is returned in vector q
and the remainder in vector
r
such that b = conv(a,q)+r
.
If b
and a
are vectors of polynomial coefficients,
convolving them is equivalent to multiplying the two polynomials,
and deconvolution is polynomial division.
