Here you can find the source of subtract(double[] accumulator, double[] values)
doubles from another.
| Parameter | Description |
|---|---|
| accumulator | The array of <code>double</code>s to subtract the elements of <code>values</code> from (the elements of this array will be modified). This may be <code>null</code>, in which case a new array will be created and initialized to zeros before subtracting the values from <code>values</code>. |
| values | The array of <code>double</code>s to subtract from each corresponding element of <code>accumulator</code>. |
