There is a difference between knowing the path and walking the path.

MpNormalize

This simple tool normalizes a wavefunction.

Computational complexity: constant

usage: mp-normalize <wavefunction>

Example

Suppose psi is some unnormalized wavefunction,

$ mp-norm psi
  1.77432

After executing
$ mp-normalize psi

we have

$ mp-norm psi
  1
