# C property

Class: rfmodel.rational
Package: rfmodel

Residues of rational function object

Vector

## Description

Complex vector containing residues of the rational function object in radians per second. Its length, shown in

$F\left(s\right)=\left(\sum _{k=1}^{n}\frac{{C}_{k}}{s-{A}_{k}}+D\right){e}^{-s\tau }\begin{array}{cc},& s=j2\pi f\end{array}$

as `n`, must be equal to the length of the vector you provide for `'A'`. `n` is the number of residues in the rational function object. This property is empty by default.

## Examples

```rat = rfmodel.rational; rat.C = [4.4896 - 4.5025i; 4.4896 + 4.5025i]*1e9; ```
