reflect a vector about a point

Hi How do I reflect a vector about a point (not the origin) in matlab?

That depends on what you intend by ‘reflect’. The rotate function might do what you want. You will have to experiment with it.

Thanks Star Strider. What I mean is I want the plot in red (enclosed figure)to be reflected along the 1st element of the plot.

I’m sorry, but I’m still no closer to understanding what you want. I still don’t understand ‘reflect’.

At this point, the detrend function comes to mind.
