Note

This tool is part of the GAMS Tools Library. Please inspect the general information about GAMS Tools.

This sorts one dimensional symbol sym and stores sorted indices in one dimensional parameter symIdx.

Usage

Command line:

gamstool [alg.]Rank sym symIdx gdxIn=fileIn.gdx gdxOut=fileOut.gdx

Compile time:

$callTool [alg.]Rank sym symIdx [gdxIn=fileIn.gdx] [gdxOut=fileOut.gdx]

Execution time:

executeTool '[alg.]Rank sym symIdx [gdxIn=fileIn.gdx] [gdxOut=fileOut.gdx]';

Where:

Argument	Description
sym	Name of parameter or set to be sorted sym(*)
symIdx	Name of parameter containing sort indexes symIdx(*)

The following named parameters are available:

Parameter	Description
gdxIn=fileIn.gdx	Name of GDX file that contains symbol sym. Mandatory if called from the command line, otherwise optional.
gdxOut=fileOut.gdx	Name of GDX file that contains symbol symIdx after execution. Mandatory if called from the command line, otherwise optional.

Example

set I /i1 * i6/;
parameter A(I) /i1=+Inf, i2=-Inf, i3=Eps, i4= 10, i5=30, i6=20/;
parameter AIndex(i) 'permutation index';

* sort symbol; result in parameter AIndex
$callTool.checkErrorLevel 'alg.Rank A AIndex'
display AIndex;
