MATLAB: How to invert the index of a vector in Simulink

Question

It is a simple question but I've been looking for a solution without luck!

Let's say I have this vector:

 v = [1 2 3]

And I want this:

 v = [3 2 1]

Is there any block that makes that?

Thanks!

Answer 1

If you have the DSP System Toolbox installed, you can use the Flip block to flip the vector horizontally. If you don't have access to this toolbox, simply use the MATLAB Function block to call fliplr instead.
