How to invert the index of a vector in Simulink?

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!

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.

Or use a Selector block with N:-1:1 index vector.

Thank you both!

This doesn't work for me. I get the input replicated identically at the output - it's not being flipped.

You can use "Math Function" block and select "Function" as "transpose".

This block is available in base MATLAB.
