## LassoNAL: version 0 -- a MATLAB software for Lasso regularized linear least squares problems

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

The software was first released on 16 September 2017. It was last updated in 16 September 2017. The software is designed to solve Lasso regularized linear least squares problems of the form:

where $\lambda>0$ is a regularization parameter, and $f(x)=\frac{1}{2}\|A(x)-b\|^2$.

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