Description

Computes the z-transform partial fraction expansion of two polynomials or transforms a given partial fraction expansion into the original polynomial representation.

Examples

Inputs

Name Description
b Specifies the coefficients in descending order of power of the numerator polynomial.
a Specifies the coefficients in descending order of power of the denominator polynomial.
r2 Specifies the residues of the partial fraction expansion. r2 is a real or complex vector.
p2 Specifies the poles of the partial fraction expansion. p2 is a real or complex vector.
k2 Specifies the coefficients in descending order of power of the quotient polynomial of a2 and b2.

Outputs

Name Description
