+//BraketDiagonal(psi1List, O, psi2List)// calculates the expectation value or matrix element  $\left\langle \psi_1[i] \mid O \mid \psi_2[i] \right\rangle$  for all  $i$ . Whereby  $I$  is the minimum of the length of the two tables. If //#psi1List// is not equal to //#psi2List// a warning is given. If psi1List or psi2List is a function instead of a list of functions the value returned is the same as one would get for //Braket//.
