It performs inverse splusp integer wavelet transform
Y = invsplusp(A,D)
Y = invsplusp(A,D,o)
A vector representing a 1-d discrete signal whose samples are integers.
A vector representing the approximation part of the integer transform.
A vector representing the detail part of the integer transform.
It regenerates the signal from its cubicsplined approximation and detail integer parts.The lengths of the approximation and detail parts is equal to the ceiling of the half of length of the input signal.
