PSS - Parameter-varying state-space model

Contents

Syntax

S = pss(Data,Domain)

Description

S = pss(Data,Domain) creates a parameter-varying state-space model defined on an N-dimensional rectangular grid. Domain is an rgrid object that specifies the N independent variables and the rectangular grid domain. Data is an N-dimensional state-space array that specifies the state space data. Data(:,:,i1,...,iN) is the model evaluated at the point Domain(i1,....,iN).

Example

% Create a 1-by-1 state-space model defined on a 1-dimensional grid
IVData = linspace(2,20,10);
Domain = rgrid('a',IVData);
for i=1:length(IVData)
  Data(1,1,i) = ss(-IVData(i),IVData(i),1,0);
end
S = pss(Data,Domain)
PSS with 1 States, 1 Outputs, 1 Inputs, Continuous System.     
The PSS consists of the following blocks:                      
  a: Gridded real, 10 points in [2,20], rate bounds [-Inf,Inf].
