**NAME**

TDSORT - A generic sorting routine, normally used indirectly (by calling the routine TDOTRI).

**SYNOPSIS**

CALL TDSORT (RWRK, NRWK, IORD, IWRK)

**C-BINDING** **SYNOPSIS**

#include <ncarg/ncargC.h> void c_tdsort(float *rwrk, int nwrk, int iord, int *iwrk)

**DESCRIPTION**

This is an internal routine used for sorting. Originally, it was not intended that a user should call this routine directly, but doing so will do no harm. Given an array of NRWK reals in an array RWRK and an "ordering flag" IORD, TDSORT returns a permutation vector IWRK such that, for every I and J such that 1.LE.I.LE.J.LE.NWRK, if IORD is zero, then RWRK(IWRK(I)).LE.RWRK(IWRK(J)), else RWRK(IWRK(I)).GE.RWRK(IWRK(J)). The arguments of TDSORT are as follows: RWRK (an input array, of type REAL, dimensioned NWRK) - an array of NWRK real numbers that are to be sorted. The contents of RWRK are returned unchanged; the ordering is as specified by the contents of the array IWRK. NWRK (an input expression of type INTEGER) - the dimension of RWRK (and of IWRK). IORD (an input expression of type INTEGER) - if IORD is zero, the desired ordering is from smallest numeric value to largest; otherwise, the desired ordering is from largest value to smallest. IWRK (an output array of type INTEGER, dimensioned at least NWRK) - returned containing a permutation of the integers from 1 to NWRK.

**C-BINDING** **DESCRIPTION**

The C-binding argument descriptions are the same as the FORTRAN argument descriptions.

**ACCESS**

To use TDSORT or c_tdsort, load the NCAR Graphics libraries ncarg, ncarg_gks, and ncarg_c, preferably in that order.
