Mpispectrum

usage: mp-ispectrum [options] <psi>
Allowed options:
  --help                show this help message
  -c [ --cart ]         show the result in cartesian coordinates [equivalent to --real --imag]
  -p [ --polar ]        show the result in polar coodinates [equivalent to --mag --arg]
  -r [ --real ]         display the real part of the result
  -i [ --imag ]         display the imaginary part of the result
  -m [ --mag ]          display the magnitude of the result
  -a [ --arg ]          display the argument (angle) of the result
  --radians             display the argument in radians instead of degrees
  -x [ --corr ]         display the equivalent correlation length
  -u [ --unitcell ] arg scale the results to use this unit cell size [default wavefunction unit
                        cell]
  -l [ --left ] arg     Calculate the expansion coefficients of this operator acting on the left
  -r [ --right ] arg    Calculate the expansion coefficients of this operator acting on the right
  --notempfile          don't use a temporary data file, keep everything in RAM (faster, but needs
                        enough RAM)
  --string arg          use this product operator as a string operator
  --conj                complex conjugate psi2
  -q [ --q ] arg        calculate the overlap only in this quantum number sector, can be used
                        multiple times [default is to calculate all sectors]
  -s [ --sort ]         sort the eigenvalues by magnitude
  --tol arg             Tolerance of the Arnoldi eigensolver [default 1e-10]
  -k [ --krylov ] arg   Length of the Krylov sequence [default 2*num-eigenvalues]
  --quiet               don't show the column headings
  --print               with --string, Print the MPO to standard output
  -v [ --verbose ]      extra debug output [can be used multiple times]
