Examples
// Discrete 1-d integer signal x=[5 6 8 9 2]; // Approximation and detail parts in integer [A,D]=cubicbspline(x) // gives a = [24. 21. 2.] // and d = [-1. 5. 1. ] |  |  |
It performs cubicbspline integer wavelet transform
[A,D] = cubicbspline(x)
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 computes the approximation and detail integer parts for a 1-d integer signal using cubicbspline integer wavelet transform. The lengths of the approximation and detail parts is equal to the ceiling of the half of length of the input signal.
// Discrete 1-d integer signal x=[5 6 8 9 2]; // Approximation and detail parts in integer [A,D]=cubicbspline(x) // gives a = [24. 21. 2.] // and d = [-1. 5. 1. ] | | |
