-//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 $i$.  +//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//.

-In Quanty //Braket(psi1, O, psi2)// is the same as // psi1 * O * psi2//. The difference is that the function //Braket// can be faster. //Braket// can work on lists of functions and then returns a matrix or vector with all possible expectation values+
