Example: Addition of Two LTI Arrays

The following diagram illustrates the addition of two 3-by-1 LTI arrays sys1+sys2.

Figure 4-8: The Addition of Two LTI Arrays

The summation of these LTI arrays

is equivalent to the following model-by-model summation:

for k = 1:3
  sysa(:,:,k)=sys1(:,:,k) + sys2(:,:,k)
end

Note that:

Each model in sys1 and sys2 must have the same number of inputs and outputs. This is required for the addition of two LTI arrays.
The lengths of the array dimensions of sys1 and sys2 must match.

The following sections describe these topics:
