Class Method Details

.new ⇒ Object

allocate instance of InterpAccel class.

This function returns a pointer to an accelerator object, which is a kind of iterator for interpolation lookups. It tracks the state of lookups, thus allowing for application of various acceleration strategies.

Instance Method Details

#reset ⇒ Object

This function reinitializes the accelerator object acc. It should be used when the cached information is no longer applicable—for example, when switching to a new dataset.
