polydata - Polynomial model parameters from single-input and single-output idpoly object

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, that is, not just idpoly. For multiple-output models you can use [A,B,C,D,F] = polydata(m(ky,:)) to obtain the polynomials for the kyth output.
