functionfromFile

Generate a TransferFunction data record by reading numenator coefficients and denominator coefficients from a file (default file name is tf.mat)

Information

Syntax

tf = TransferFunction.Import.fromFile(fileName, numName, denName)

Description

Reads and loads a transfer function from a mat-file fileName. The file must contain the names of the vector with the polynomial coefficients of numerator and denominator

Example

algorithm
  tf:=Modelica_LinearSystems2.TransferFunction.Import.fromFile("tf.mat", "n", "d");
//  tf = (s^2 + 2*s + 3)/(4*s^2 + 5*s + 6)

Inputs

Type	Name	Default	Description
String	fileName	"tf.mat"	Name of the transfer function data file
String	numName	"n"	Name of the numenator of the transfer function
String	denName	"d"	Name of the denominator of the transfer function

Outputs

Type	Name	Default	Description
TransferFunction	tf		transfer function
