Hi, I've been trying to write a program to solve a propagation of a wave packet using the time dependent schrodinger equation. and I noticed I would need to use complex numbers. I know that I need to use #include<complex> I declare my array, and I started with a simple 1-d array. complex<double>a When inputting data to the array I know that I would need something like this: a = (1,5); a = (2,8); however when I output the data I only get: a = (5,0) a = (8,0) Any idea how I can get around it? And what about taking the complex conjugate of an array?
