Jack, I installed Julia 0.5.0 on my Linux Mint 17.3 "Rosa" MATE 64-bit machine a few days ago, but when I run your code (and Allin's code from Saturday before last), I get this: gretl version 2015e-git Current session: 2016-01-20 19:47 ? matrix X = mnormal(6,6) Generated matrix X ? mwrite(X, "X.mat") ? foreign language=julia julia: unknown language Data error Error executing script: halting Thoughts?
