A Multidimensional Discrete Variable Representation Basis Obtained by Simultaneous Diagonalization
A multidimensional discrete variable representation basis obtained by simultaneous diagonalization was proposed. the DVR spanned the same space as a contracted basis, but the matrix representations of the coordinates were diagonal. the DVR basis functions were chosen to achieve maximal diagonality of coordinate matrices. the accuracy of the DVR was also assessed by applying it to model four dimensional problems.
