Purpose Build an LTI array b y stacking LTI models or LTI arrays along array
dimensions of an LTI array
Syntax sys = stack(arraydim,sys1,sys2,...)
Description sys = stack(arraydim,sys1,sys2,...) produces an array of LTI models sys
by stacking (concatenating) the LTI models (or LTI arrays) sys1,sys2,...
alongthearraydimensionarraydim. All models must have the same number
of inputs and outputs (the same I/O dimensions). The I/O dimensions are not
counted in the array dimensions. See “Dimensions, Size, and Shape of an LTI
Array” on page 4-7, and “Building LTI Arrays Using the stack Function” on
page 4-15 for more information.
Example If sys1 and sys2 are two LTI models with the same I/O dimensions:
•
stack(1,sys1,sys2) produces a 2-by-1 LTI array.
•
stack(2,sys1,sys2) produces a 1-by-2 LTI array.
•
stack(3,sys1,sys2) produces a 1-by-1-by-2 LTI array.
