Example 1: Sorting

using System;
using Imsl.Math;
using Imsl.Stat;

public class SortEx1
{
	public static void  Main(String[] args)
	{
		double[] ra = new double[]{  10.0, - 9.0, 8.0, - 7.0, 6.0,
									  5.0, 4.0, - 3.0, - 2.0, - 1.0};
		int[] iperm = new int[]{0, 1, 2, 3, 4, 5, 6, 7, 8, 9};
		
		PrintMatrix pm = new PrintMatrix("The Input Array");
		PrintMatrixFormat mf = new PrintMatrixFormat();
		mf.SetNoRowLabels();
		mf.SetNoColumnLabels();
		//	Print the array
		pm.Print(mf, ra);
		Console.Out.WriteLine();
		
		//  Sort the array
		Sort.Ascending(ra, iperm);
		
		pm = new PrintMatrix("The Sorted Array - Lowest to Highest");
		mf = new PrintMatrixFormat();
		mf.SetNoRowLabels();
		mf.SetNoColumnLabels();
		
		//	Print the array
		pm.Print(mf, ra);
		
		pm = new PrintMatrix("The Resulting Permutation Array");
		mf = new PrintMatrixFormat();
		mf.SetNoRowLabels();
		mf.SetNoColumnLabels();
		//	Print the array
		pm.Print(mf, iperm);
	}
}
