I had a list of complex numbers that I wanted to find the argument of. Instead of individually inputting each complex number, I was told I could use:

argument~([complexn1,complexn2,complexn3]);

This gave me the argument approximations for each of the complex numbers. When I removed the tilde however, I got an error saying that the argument command could only deal with 1 complex number at a time.

What did the tilde do that allowed me to find all the arguments at once?
