I have a small issue.
Just wondering if there is a easy way to transform an entire matrix of any size from `"/laser"` to `"/map"` frames.
In advance thank you.

https://answers.ros.org/question/154666/transform-a-matrix-with-tf/?comment=173716#post-id-173716What kind of representation are you using? You will probably need to write your own code for this. But it should be pretty easy - just use TF for point 0,0 of your matrix and that's it, am I right?Mon, 16 Jun 2014 06:47:08 -0500https://answers.ros.org/question/154666/transform-a-matrix-with-tf/?comment=173716#post-id-173716Comment by acp for <p>Hi all,</p>

https://answers.ros.org/question/154666/transform-a-matrix-with-tf/?comment=155981#post-id-155981well, I have a matrix that represents a map in the laser frame and I want to be seen by the map frame, or in other words, transform the matrix from laser to mapMon, 21 Apr 2014 21:53:12 -0500https://answers.ros.org/question/154666/transform-a-matrix-with-tf/?comment=155981#post-id-155981Comment by demmeln for <p>Hi all,</p>
