It performs inverse of (9,7) integer wavelet transform.
y = invnine7(a,d)
A 1-d signal representing the approximation part.
A 1-d signal representing the detail part.
A 1-d vector representing the reconstructed signal. Its length is twice the length of approximation or detail part.
It performs the reconstuction of a signal from its approximation and detail parts. It tkes two or three inputs. The first two inputs corresponds to the approximation and the detail parts.
// input x=[3 5 2 6 7 1 9]; // approximation and detail parts [a,d]=nine7(x); // gives a=[0. 0. 7. 9. ] and d=[0. - 3. - 4. 0.] // Reconstruction y=invnine7(a,d); // gives y= [3. 5. 2. 6. 7. 1. 9. 0.] Add here scilab instructions and comments | ![]() | ![]() |
