hi
I need to know if there is any method for norm2 and norm1 directly in c# , as you know these functions are used in math for vectors ... but is there any method in C# that can do so?

Solution 2

The latest .net framework 4.5 provides a method Normalize() in Vector class.
http://msdn.microsoft.com/en-us/library/system.windows.vector.normalize.aspx[^]
Have a look on the above link. There is a nice article which explains many things about vectors and vector normalization.
A Vector Type for C#[^]

If you really want a method Normalize in the previous frameworks, then use the above link, understand it and create an extension method Normalize().

public static void Normalize(this Vector vectorObj,...)
{
    /// write the normalization logic here
}

I hope you were looking for the same.

thanks every one, unfortunately I could't fined the answer , so i start do it myself here is what I hope is right :

C#

public double norm2(double[] x)
     {
         double sum = 0;
         double norm2 = 0;
         for (int i = 0; i < x.Length; i++)
             sum = x[i] * x[i];
         norm2 = Math.Sqrt(Math.Abs(sum));
         return norm2;


     }

Solution 1

The Math namespace has all the methods on offer, such as Math.Round and Math.Floor. If it's not there, it's not there, and you need to write it.
