I do understand how to use PyWavelets.For example if i have the following code:
cA,cD = pywt.dwt(yourResultA,'db3')
The value stored in cA and cD would be approximation coeff. and details coeff. respectively. Is the value stored in cA that of 4th approximation coeff(A4) ? Another problem that I am facing is that I want the values of all the details coeff i.e. D1,D2....D4. How can I get these values from cD?
