Hi,
I've just found this library and seems pretty good, congratulations! I see that you support group lasso and I was wondering if there was a plan for supporting sparse group lasso, since that sho…

Hi,
I would like to leverage Pylops for the domain of 'phase retrieval', but I don't know how to start on this. A typical phase retrieval problem has the following form:
`|| y - | F^-1{ K * F{x}…

Hi, thank you for this nice repo :)
Is there any way to use it to do positive group lasso, that is minimizing over vector with non-negative coefficients ?
In scikit-learn, there is a ```positive=T…

Dear Edouard and Mathieu,
I have made a proposed solution to the problem of both passing and returning information about the algorithm through the same data structure.
My proposed solution is to pas…
