[ Top ] [ Modules ]

NAME

  Module tri_croissant

USAGE

  use tri_croissant

DESCRIPTION

  This module is used to sort an integer array or shift its elements by certain amount

OUTPUT

  This module exports:
  * tri_int -- a subroutine to sort out an integer array
  * shift_param -- a subroutine to shift (modulo n) the elements of an integer array

USES

  * precision_golem (src/module/precision_golem.f90)

src/module/tri_croissant/exchange_param [ Functions ]

[ Top ] [ Functions ]

NAME

  Subroutine exchange_param

USAGE

  call exchange_param(z_param_ini,tab,modd,z_param_out)

DESCRIPTION

  This routine exchanges in the array z_param_ini of Feynman parameters
  the label tab(1) with the label tab(2)
  the result is put into the array z_param_out

INPUTS

  * z_param_ini -- an integer array of rank 1, the array to shift
  * tab -- an integer array of rank 1, the two labels to exchange
  * modd -- an integer, the shift is made modulo modd

SIDE EFFECTS

  No side effect

RETURN VALUE

  * z_param_out -- an integer array of rank 1, the shifted array

EXAMPLE


src/module/tri_croissant/shift_param [ Functions ]

[ Top ] [ Functions ]

NAME

  Subroutine shift_param

USAGE

  call shift_param(z_param_ini,shift,modd,z_param_out)

DESCRIPTION

  This routine shifts the array z_param_ini of Feynman parameters
  the shift is done as following: 
  z --> z+shift if z+shift <= modd 
  else mod(z+shift-1,modd)+1 if z+shift > modd
  the result is put into the array z_param_out

INPUTS

  * z_param_ini -- an integer array of rank 1, the array to shift
  * shift -- an integer, the value of the shift
  * modd -- an integer, the shift is made modulo modd

SIDE EFFECTS

  No side effect

RETURN VALUE

  * z_param_out -- an integer array of rank 1, the shifted array

EXAMPLE


src/module/tri_croissant/tri_int [ Functions ]

[ Top ] [ Functions ]

NAME

  Subroutine tri_int

USAGE

  call tri_int(t_in,t_out)

DESCRIPTION

  This routine sorts in increasing order an integer array t_int and put the 
  result in the integer array t_out

INPUTS

  * t_int -- an integer array of rank 1, the array to sort

SIDE EFFECTS

     NONE

RETURN VALUE

  * t_out -- an integer array of rank 1, the sorted array
