How do you add of two signal in matlab?

To add two signals in MATLAB, you can simply use the plus operator (+). For example, if you have two signals stored in arrays signal1 and signal2, you can add them together using result = signal1 + signal2;. Ensure that both signals have the same length; otherwise, MATLAB will return an error due to dimension mismatch. After adding, you can plot the result using the plot function for visualization.
