Modules
module	sort_oct_m
	This module is intended to contain "only mathematical" functions and procedures.

Data Types
interface	sort_oct_m::robust_sort_by_abs
interface	sort_oct_m::sort
	This is the common interface to a sorting routine. It performs the shell algorithm, not as fast as the quicksort for large numbers, but it seems that better for moderate numbers (around 100). Their possible interfaces are: subroutine sort(a [, ind]) real(real64),_OR_INTEGER, intent(inout) :: a(:) integer, intent(inout), optional :: ind(:) ! This routine sorts, from smallest to largest, the array a. ! If the integer array ind is present, it puts in it the indexing ! of the sorting, so that other arrays can be sorted according to ! the sorting of a. end subroutine sort. More...
