4.7. Polynomial Division
Generally, deconv function is used to deconvolve two vectors. In case vectors are coefficients of two polynomials, then function deconv gives polynomial division and it returns the quotient as well as remainder. The syntax is given as
[x, r] = deconv(z, y)
where
z is the dividend vector,
y is the divisor vector,
x specifies the vector of quotients obtained, and
r specifies the vector of remainders obtained.
Example 4.8.

Divide the polynomial z by y where z = s3 + 6s2 + 16s + 16 and y = s2 + 4s + 8. Solution: The polynomials z and y are represented by the two vectors: z = [1 6 16 16]; y = [1 4 8]; The command used for division is [x, r] = deconv (z, y) The resultant polynomial x and remainder r obtained are x = 1 2 r ... |
