can i have code to plot an ECG after add unlimited noise removes the baseline wander in ecg signal by using the wavelet transform ?

hi, i am haneen . i am new this is my first question. please help me to arrival of my target . My experience in matlab is very limited. my objective: step 1: plot original ECG. step 2: add random (unlimited) noise (baseline wander)to ECG(in step 1). step 3: removes the baseline wander by using wavelet transform. thanks alot

When you indicate "unlimited noise" you probably mean "normal distribution", which can be generated by randn() . randn() does not produce truly unlimited values because MATLAB cannot represent values between 10^309 and infinity.
