Re: det(A+ tB)



Jon Slaughter a écrit :
det(A + tB) = det(A B^-1 + t I) * det(B)

(the notation A/B used by one poster should be strongly denigrated),

and why is that? You have such a strong feeling to say such a comment about it so what is the reason? Is it not to hard to see that A/B = A*B^(-1). Sure it might be symbolically different about its 1/5 of the number of symbols to write and just adds confusion when typing in ASCII with no benefit. So you might not like it but thats tough unless you can give a good reason against it.


How do you note B^(-1)*A ? Is it A\B ?

A/B is clear and concise while A*B^(-1) is not(and here
I'm specifically talking about when it is written in ASCII).

So please do tell me why the short hand A/B is such a bad thing that it has to be denigrated.
