I'm interested in the use/application of the trace of a square matrix?
I am trying to get an intuitive feel for what it 'means' . . .
Along the lines of: for a 2x2 matrix, the determinant represents the area of the parallelogram.
I know it is the sum of the entries of the diagonal of a square matrix, but is there some practical, everyday, easy to understand, example of how the trace is used?
