cubicbspline

It performs inverse cubicbspline integer wavelet transform

Calling Sequence

Y = invcubicbspline(A,D)

Arguments

Y

A vector representing a 1-d discrete signal whose samples are integers.

A

A vector representing the approximation part of the integer transform.

D

A vector representing the detail part of the integer transform.

Description

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.

Examples

// Approximation part of a cubicsplined signal.
    A=[24.  21.  2.];
// detail parts in integer
    D= [-1.  5.  1.];    
    Y = invcubicbspline(A,D)
// gives Y=[5 6 8 9 2]
