Method Detail

average

public static java.util.Vector<java.lang.Number> average(java.util.Collection<java.util.Vector<java.lang.Number>> items)

sum

public static java.util.Vector<java.lang.Number> sum(java.util.Collection<java.util.Vector<java.lang.Number>> items)

Returns:

a vector of numbers with dimension equal to the smallest dimension of any of the items, or null if items is empty. (returns null on empty input because the dimensionality of the vector would otherwise be undefined.)

divide

public static java.util.Vector<java.lang.Number> divide(java.util.Vector<java.lang.Number> numerator,
                                                        double divisor)
