Fill the ICloud2D with a couple of values and a corresponding weight. If either a coordinate or the weight is NaN the entry will be recorded but it will not contribue to the statistics.

Parameters:

x - The x value.

y - The y value.

Throws:

IllegalArgumentException - If the ICloud2D is full or if the weight's value is not between 0 and 1.

weight

public double weight(int index)
              throws AlreadyConvertedException

Get the weight corresponding to a given entry.

Parameters:

index - The entry's index.

Returns:

The weight of the index-th entry.

Throws:

AlreadyConvertedException - If the ICloud has already been converted.

meanX

public double meanX()
