Arythemtics

Static codes support two types arithmetics:

• double complex: ESIZE=16B
  default mode: matrix elements of hamiltonian are assumed to be of complex numbers.
• double: ESIZE=8B
  if you know that matrix elements, as well as the solution, will be real numbers (for examples based on symmetries of your problem) you can speed-up the calculation process by switching to double arythmetics. To do this you need to activate in predefines.h flag:

/**
 * activate this if you know that Hamiltonian matrix is real, 
 * the code will utilize it in order to speed-up the calculations
 * */
#define MATRIX_IS_REAL

3D version of the code diagonalized matrix of size: matrix_size = NX*NY*NZ*2.
