public static final Transformer UNINITIALIZED
This transformer is used when we initialize the filter, until we get at least one non-zero value to select the proper transformer.
public static final Transformer PLUS
When this transformer is applied, the roots of the original function
are preserved, with the same increasing/decreasing
status.
public static final Transformer MINUS
When this transformer is applied, the roots of the original function
are preserved, with reversed increasing/decreasing
status.
public static final Transformer MIN
Precision.SAFE_MIN
, -g, +g).
When this transformer is applied, the transformed function is guaranteed to be always strictly negative (i.e. there are no roots).
public static final Transformer MAX
Precision.SAFE_MIN
, -g, +g).
When this transformer is applied, the transformed function is guaranteed to be always strictly positive (i.e. there are no roots).
