Example 1: Minimum of a smooth function

using System;
using Imsl.Math;

public class MinUnconEx1 : MinUncon.IFunction
{
    public double F(double x)
    {
        return Math.Exp(x) - 5.0 * x;
    }


    public static void  Main(String[] args)
    {
        MinUncon zf = new MinUncon();
        zf.Guess = 0.0;
        zf.Accuracy = 0.001;
        MinUncon.IFunction fcn = new MinUnconEx1();
        Console.Out.WriteLine("Minimum is " + zf.ComputeMin(fcn));
    }
}

Output

Minimum is 1.60941759992002
