plot (idmodepolydata)

Convert a model to input-output polynomials.

Syntax

• [A,B,C,D,F] = polydata(m)
  [A,B,C,D,F,dA,dB,dC,dD,dF] = polydata(m)
  

Description

This is essentially the inverse of the idpoly constructor. It returns the polynomials of the general model

as contained in the model m.

dA, dB etc. are the standard deviations of A, B, etc.

m can be any single output idmodel, i.e., not just idpoly. For multi-output models you can use [A,B,C,D,F] = polydata(m(ky,:)) to obtain the polynomials for the ky-th output.
