Remove Baseline wander using for ECG or PPPG

A program in Matlab to Remove Baseline wander using "Wavelets"

%% TASK UNDER PROGRAM 3:
% PROCEED PROGRAM 3 ONLY AFTER COMPLETION OF PROGRAM 1 & 2
% (3-a) Use Subplot to show wavelet decomposition for d1,a1,d2,a2 and label
% the frequency values for the same
% (3-b) Use Subplot to show wavelet decomposition for d3,a3,d4,a4 and label
% the frequency values for the same .
% (3/1) Try using other wavelets (db1,db2,db3,db4,db5,db6)- Note the
% differences observed
