I have a table that has multiple columns. See below.

I want to remove the rows that don't satistfy this condition: frame_id != "map" AND child_frame_id != "drone_base".

The remaining array should contain the "x" values of the remaining rows whose frame_id == "map" AND child_frame_id == "drone_base".

How would I go about doing that?

 tYourTable=tYourTable(contains(tYourTable.frame_id,"map")&contains(tYourTable.child_frame_id,"drone_base"),:);

@dpb I am receiving this error: Undefined function or variable 'frame_id'.

I can see what you're doing. Shouldn't you use tYourTable.frame_id and tYourTable.child_frame_id to access the content of the two columns?

Yeah -- I had a typo originally and then didn't cut 'n paste enough...
