So today I'm trying to play around with matrix norm until I've come across this "bug" (I assume)... with(LinearAlgebra): r:=Matrix([2*x,x^2,x^3/3]); dr:=Matrix(map(diff, r, x)); MatrixNorm(r,2); MatrixNorm(dr,2); My question is that why does Maple spit out "x" and "xbar" while obviously, it should all be "x". And what's the command to make it just in terms of "x"
