Is there a way to find the area between to graphs in simulink?

4 views (last 30 days)
I have two graphs, where i want to find the area between them in Simulink. However i cant seem to find out how to do it. Is there a way to do this in the scope, or how can this be achieved.
It is the area between the blue and yellow graph, and in between the white lines.
Best regards

Well, I would use toWorkspace in SImulink and export these variables to workspace. Then I would perform integration there by writing appropriate script.

In Simulink, subtract yellow signal from the blue signal and then feed it to an integrator block. That will give you the area between the two lines. Note that there will be a positive/negative sign and the integration might cancel each other.
You could take the absolute value after the subtraction if you truly want the "area".
You could use triggered subsystem to calculate the area between the two while lines (on time axle), or do it manually by subtracting the integration value at those two time points.
