====== N ====== ### unsigned integer, read only ### ### 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 ==== NF=3 NB=0 psi = NewWavefunction(NF, NB, {{"110",sqrt(1/4)},{"101",sqrt(1/4)},{"011",(1+I)*sqrt(1/4)}}) print(psi.N) ==== Result ==== 3 ===== Available properties ===== {{indexmenu>.#1}}
