Use point data to plot a signal to use in Simulink

Hi,

The attached file is a plotting of earthquake wave drawn with many points. Is there a way that I change this into a signal (like sine wave/signal generator) to be used in Simulink?

Thanks for help in advance.

The following procedure might help you:

1. In the MATLAB command prompt run your script and then open Simulink.
2. Create a blank model and add a Signal Builder block.
3. Double click the Signal Builder block.
4. Select Signal > New > Custom.
5. In the Custom Waveform window, enter t in the Time values field and y in the Y values field and then click OK.

The Signal Builder block window displays the new signal as Signal 2.
