Currently we have two tags matrix and linear-algebra. These tags have a rather large overlap, in fact (after a clean up) of the 30 questions tagged linear-algebra the following are the questions not tagged with matrix
And all of these questions are not about matrices, (however some do have methods of solution that involve matrices.)
On the other hand matrix, has about 100 questions with only 25 of them being tagged linear-algebra.
Should one of these tags be a synonym of the other? If so which one?
