NAME

  Module kronecker

USAGE

  use kronecker

DESCRIPTION

  This module contains two functions delta and deltab which correspond 
  respectively to the Kronecker symbol \delta_{ij}
  and 1-\delta_{ij}. These two functions have two integer arguments and 
  return an integer

OUTPUT

  This module exports two functions:
  * delta -- the Kronecker symbol
  * deltab -- 1-delta

USES

  No uses

src/module/kronecker/delta [ Functions ]

[ Top ] [ Functions ]

NAME

  Function delta

USAGE

  integer = delta(i,j)

DESCRIPTION

  This is the Kronecker symbol \delta_{ij}

INPUTS

  * i -- an integer
  * j -- an integer

SIDE EFFECTS

  No side effect

RETURN VALUE

  It returns an integer 0 or 1

EXAMPLE

  k = delta(2,3) --> k = 0
  k = delta(3,3) --> k = 1

src/module/kronecker/deltab [ Functions ]

[ Top ] [ Functions ]

NAME

  Function deltab

USAGE

  integer = deltab(i,j)

DESCRIPTION

  This is one minus the Kronecker symbol, 1-\delta_{ij}

INPUTS

  * i -- an integer
  * j -- an integer

SIDE EFFECTS

  No side effect

RETURN VALUE

  It returns an integer 0 or 1

EXAMPLE

  k = deltab(2,3) --> k = 1
  k = deltab(3,3) --> k = 0
