This program implements the cvxEDA algorithm for the analysis of electrodermal activity (EDA) using methods of convex optimization, described in:

IEEE Transactions on Biomedical Engineering, 2015
It is based on a model which describes EDA as the sum of three terms: the phasic component, the tonic component, and an additive white Gaussian noise term incorporating model prediction errors as well as measurement errors and artifacts.
This model is physiologically inspired and fully explains EDA through a rigorous methodology based on Bayesian statistics, mathematical convex optimization and sparsity.

how to add my samples in this code?
Helpful matlab function to explore and analyze EDA signal. I tried to use it on my samples, so far so good until I got negative value for tonic part. I have no experience working with EDA signal but I think it is impossible. Would you explain me this phenomenon? Thank you.
