-alligned paragraph text+//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 $i$.  
 + 
 +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
