I am using a class that i downloaded from: http://www.codeproject.com/KB/recipes/K-Mean_Clustering.aspx
And in the class Kmeans. They say that this function:
/// Returns the one dimensional array data located at the index
public virtual double  this[int Index]
//return the Neuron at IList[Index]
I don't understand how to get the list. it's the first time that i see this in c# i am really new. Thank you.
