Close the dialog box by clicking on the OK button or by pressing Enter on
the keyboard.
b Double-click on the Matrix Sum block. Select Rows from the Sum along
parameter, and close the dialog box.
You can now move on to the model simulation phase.
Model Simulation
Simulink is also a model simulation environment. You can run the simulation
block diagram that you have built to see how the system behaves. To do this:
1 Select Signal dimensions from the Format menu (optional). The symbol
“
[1x2]” appears on the output line from Sine Wave indicating that the
output is a 1-by-2 matrix.
At each sample time, the output matrix contains one sample from each of the
two sinusoids. The Matrix Sum block adds the two matrix elements together
