Select Input/Output Pairs in MIMO Models

This example shows how to select the response from the first input to the second output of a MIMO model.

1. Create a two-input, one-output transfer function.

   N = {[1 -1],[1];[1 2],[3 1 4]}; 
   D = [1 1 10]; 
   H = tf(N,D)

   Note

   For more information about using cell arrays to create MIMO transfer functions, see the tf reference page.

2. Select the response from the second input to the output of H.

   To do this, use MATLAB^® array indexing.

   H12 = H(1,2)

   For any MIMO system H, the index notation H(i,j) selects the response from the jth input to the ith output.
