Parameter

Parameter	Description
accumulator	The array of <code>double</code>s that is to have its elements scaled (the elements of this array will be modified).
offset	The index into <code>accumulator</code> at which to start multiplying by elements of <code>modulator</code>.
modulator	The array of <code>double</code>s by which to multiply each corresponding element of <code>accumulator</code>.

Return

A reference to accumulator.

Declaration
