Constructing Signals
3-51
To build the model, define the following variable in the MATLAB workspace.
A = [1 1 5 -1;2 1 5 -2;3 0 5 -3;405-4;515-5;615-6];
Connect the Buffer block to a Signal From Workspace source and a To
Workspace sink with the following parameter settings:
•In the Signal From Workspace block, set:
-
Signal = A
- Sample time = 1
- Samples per frame = 1
•In the Buffer block, set:
-
Output buffer size (per channel) = 3
- Buffer overlap = 1
- Initial conditions = 0
Note that the inputs do not begin appearing at the output until the second row
of the second matrix. This is due to the block’s latency. See “Delay and Latency”
on page 3-85 for general information about algorithmic delay, and see
“Buffering Delay and Initial Conditions” on page 3-53 for instructions on how
to calculate buffering delay.
