If you think that this doesn't belong to the standard, then please allow me to ask one question: Why is there a complex number class in the standard and what does it actually do?
There is rather less discussion about possible interfaces for complex numbers than for matrices. (The last time I used matrices in my code, I wanted A=B*C to mean A[i,j] = B[i,j]*C[i,j].)
Interesting: that's a direct product, which we hardly ever use. This supports my statement up-thread that while matrices in general are well known and commonly used, getting any two people to agree on the interface is difficult, because people use them so differently. That statement is not true of complex numbers, which pretty much everyone uses the same way. -- Dave Steffen - Software Engineer 4 Numerica Corporation (www.numerica.us <http://www.numerica.us/> ) Email: dave.steffen@numerica.us
