I need all scaled and translated versions of the Daubechies D4 mother wavelet (also known as the daughter wavelets) for data analysis. I cannot find any information or MATLAB functions that allow the daughter wavelets as an output in MATLAB. Please let me know if (1) I can obtain the daughter wavelets from MATLAB or (2) I can calculate the DB4 daughter wavelets manually after wavelet decomposition. Thank you so much for your help.

The following links should be helpful to obtain Daubechies wavelets :
