I have not used it. However, it can be downloaded as glmnet_matlab.zip so you most likely need to unzip it to a sub-directory on your MATLAB search path (see: What is the MATLAB Search Path? for details), add that directory to your MATLAB search path so MATLAB can find the folder, then use it as referred to in the Glmnet documentation.

I used glmnet in matlab a couple of years ago but I haven't used it for a while.
As far as I know, the glmnet only works for older versions of matlab(< 2016).
It is a shame because glmnet works much faster than lassoglm.

Also, @Star Strider, options.alpha doesn't set a significance value, it is a mixing parameter between a lasso-regularized vs ridge-regularized GLM. alpha = 0 is lasso, alpha = 1 is ridge

I can confirm that this works on Matlab 2019a, but it requires a fortran compiler (I used Intel Parallel Studio XE 2019, which unfortunately required me to register for a free student trial to install).
First download the glmnet package, unzip it and add it to the matlab path. Then install a fortran compiler that works with your version of Matlab and OS.
Once you have set mex -setup to use this compiler (I think the command was:
mex -setup fortran
run the mexAll.m script in the glmnet folder.
This is what worked for me on Mac OSX 10.14.6 on Matlab2019a

This worked, but I had to install Microsoft Visual Studio before the student trial of Intel Parallel Studio XE 2019. Thank you!
