Dear Sirs, I was reading your specs for MathML, and I noticed that there was no operator defined for the trace operation on matrices. (The trace of a square matrix is the sum of the diagonal entries of the matrix.) While the trace of a matrix is not used as frequently as the determinant, I think that it is used often enough that a content markup element be defined for it. Thank you, Joe GottmanReceived on Tuesday, 7 March 2000 14:28:02 UTC
