## SuiteLasso: a MATLAB suite for regression problems with generalized Lasso regularizers

### Xudong Li, Defeng Sun and Kim-Chuan Toh

The software was first released on January 2019. It was last updated in January 2019. The software is designed to solve linear least squares problems with various generalized lasso regularizers. Currently, it can handle the following regularizers:

1. Classic Lasso

Solver: ClassicLasso_SSNAL.m

2. Fused Lasso

where $\lambda>0$ and $\beta >0$ are regularization parameters, and $h(x)=\frac{1}{2}\|x-b\|^2$.

Solver: FusedLasso_SSNAL.m

Important note: this is a research software. It is not intended nor designed to be a general purpose software at the moment.
