Is it possible to compute the discrete wavelet transform by convolving the input signal with a specific wavelet (at different scales) in MATLAB/python
Below is a diagram of how I plan to do the DWT. How can this be done using Matlab? I do not want to this by sub band coding.
Solution
This is how got used to the discrete wavelet transform in MATLAB https://au.mathworks.com/help/wavelet/, the above is the link for the Wavelet toolbox for MATLAB. Check out the below functions.

PS if you do not want the decimation of samples at each stage, try out the stationary wavelet transform in MATLAB. ( makes your results redundant according to my understanding.) https://au.mathworks.com/help/wavelet/ref/swt.html
