An adaptive FIR filter with a lattice structure. This class extends
the base class to dynamically adapt the reflection coefficients to
minimize the power of the output sequence. The output reflection
coefficients are guaranteed to lie between -1.0 and 1.0, ensuring that the
resulting filter is a minimum phase linear predictor. The
reflectionCoefficients parameter is interpreted as the initial
coefficients.

adaptedReflectionCoefficients
The output port that produces the current reflection
coefficients. The port is of type array of double.
timeConstant
The time constant of the filter, which determines how fast the
filter adapts.
The default value of this parameter is 1.0.
