deconv
Deconvolution and polynomial division.
Syntax
- [q, r] = deconv(b, a)
Input argument
- a - row or column vectors
- b - row or column vectors
Output argument
- q - quotient: row or column vector
- r - remainder: row or column vector
Description
[q, r] = deconv(b, a) performs deconvolution on vector b by vector a using long division.
It returns the quotient q and remainder r such that b = conv(a, q) + r.
In the context of polynomial coefficients, deconvolving vectors b and a is akin to dividing the polynomial represented by b by the polynomial represented by a.
Example
b = [1; 2; -1]; % Dividend (x^2 + 2x - 1)
a = [1; 1]; % Divisor (x + 1)
[q, r] = deconv(b, a)
