Hi, I need some help
I am trying to sort a list of complext number, say, List={a+b*I, c+d*I};
and I want a>c and b>d. I know that Sort can do this with a small list of
complex numbers, but what I deal with is a list of about 100000 and maybe
more, and it doesn't seem to work with the imaginary part when you just
Sort[List],
Does anyone have a small program to do this?
thank you
