Deconvolution and polynomial division
Syntax
[q,r] = deconv(v,u)
Description
[q,r] = deconv(v,u)
deconvolves vector u out of vector v, using long division. The quotient is returned in vector q and the remainder in vector r such that v = conv(u,q)+r.
If u and v are vectors of polynomial coefficients, convolving them is equivalent to multiplying the two polynomials, and deconvolution is polynomial division. The result of dividing v by u is quotient q and remainder r.
Examples
u = [1 2 3 4] v = [10 20 30]
c = conv(u,v)
c =
10 40 100 160 170 120
Use deconvolution to recover u:
[q,r] = deconv(c,u)
q =
10 20 30
r =
0 0 0 0 0 0
This gives a quotient equal to v and a zero remainder.
Algorithm
deconv uses the filter primitive.
