What does your "wandering baseline" look like? does it just look like linear trend? piecewise linear?
If so, you can just use detrend() with 'linear'. You can supply a vector of breakpoints if you want to remove a piecewise linear trend.

I use data from mitbih database which are .mat, .info and .hea, then plot lead I and lead avF.
How to remove noise and make correction of baseline wandering from 0 point?
