functionfromFile
Generate a ZerosAndPoles record by reading the polynomial coefficients or zeros and poles from a file
Information
Syntax
| zp | = | ZerosAndPoles.Import.fromFile(fileName) |
Description
Reads and loads a zeros-and-poles transfer function from a mat-file fileName. The file must contain either the set of variables n1, n2, d1, d2, and k with the associated first and second order polynomials or the variables p, z, and k with the poles and zeros, written in two column arrays with real and imaginary in the first and second column respectively. The variable k is the real gail in both cases.
Example
algorithm
zp:=Modelica_LinearSystems2.ZerosAndPoles.Import.fromFile("zp.mat", "n", "d");
// zp = (p^2 + 2*p + 3)/(p + 2)/(p^2 + 2*p + 2)
