`linspace` error with bad inputs

I'm not exactly sure what causes this but it seems like this error shouldn't occur. I would expect just a failure to converge?

If you put an intercept in the design matrix and don't set intercept=false, the full model is rank-deficient. In general you probably don't want an L1 penalty on the intercept. See #11
