L=12000, I have two methods to do an optimization problem. The first method needs to store L^2 double complex numbers in total, and requires L^2 multiplications of double complex numbers in each iteration. The second method needs to store 5*L double complex numbers in total, and requires 3*L^2 multiplications of double complex numbers in each iteration. I wonder which one is better.
