| + | returns the number of determinants saved within the wavefunction. | ||
| + | ### | ||

| + | ===== Example ===== | ||
| + | |||
| + | ### | ||
| + | We can define the function: | ||
| + | $$ | ||
| + | |\psi\rangle = \left(\frac{1}{\sqrt{4}} a^{\dagger}_0 a^{\dagger}_1 + \frac{1}{\sqrt{4}} a^{\dagger}_0 a^{\dagger}_2 + (1+I)\frac{1}{\sqrt{4}} a^{\dagger}_1 a^{\dagger}_2 \right)|0\rangle, | ||
| + | $$ | ||
| + | which has three determinants and //psi.N// thus is equal to three. | ||
| + | ### | ||

| + | ==== Input ==== | ||
| + | <code Quanty Example.Quanty> | ||

| + | NB=0 | ||
| + | psi = NewWavefunction(NF, | ||
| + | print(psi.N) | ||
