repsys - Replicate and tile models

Syntax

Description

rsys = repsys(sys,[M N]) replicates the model sys into an M-by-N tiling pattern. The resulting model rsys has size(sys,1)*M outputs and size(sys,2)*N inputs.

rsys = repsys(sys,N) creates an N-by-N tiling.

rsys = repsys(sys,[M N S1,...,Sk]) replicates and tiles sys along both I/O and array dimensions to produce a model array. The indices S specify the array dimensions. The size of the array is [size(sys,1)*M, size(sys,2)*N, size(sys,3)*S1, ...].

Tips

rsys = repsys(sys,N) produces the same result as rsys = repsys(sys,[N N]). To produce a diagonal tiling, use rsys = sys*eye(N).

Input Arguments

sys	Model to replicate.
M	Number of replications of sys along the output dimension.
N	Number of replications of sys along the input dimension.
S	Numbers of replications of sys along array dimensions.

Output Arguments

rsys	Model having size(sys,1)*M outputs and size(sys,2)*N inputs. If you provide array dimensions S1,...,Sk, rsys is an array of dynamic systems which each have size(sys,1)*M outputs and size(sys,2)*N inputs. The size of rsys is [size(sys,1)*M, size(sys,2)*N, size(sys,3)*S1, ...].

Examples

Replicate a SISO transfer function to create a MIMO transfer function that has three inputs and two outputs.

sys = tf(2,[1 3]);
rsys = repsys(sys,[2 3]);

The preceding commands produce the same result as:

sys = tf(2,[1 3]);
rsys = [sys sys sys; sys sys sys];

Replicate a SISO transfer function into a 3-by-4 array of two-input, one-output transfer functions.

sys = tf(2,[1 3]);
rsys = repsys(sys, [1 2 3 4]);

To check the size of rsys, enter:

size(rsys)

This command produces the result:

3x4 array of transfer functions.
Each model has 1 outputs and 2 inputs.
