math.inv() causes "Can not calculate inverse, determinant is zero"

[hogegex]

The following simple code works fine with mathjs v4.4.0, but it throws an exception in v4.4.1.

let mat = math.matrix ([
   [1, 0, 0],
   [0, -1, 1],
   [0, 0, 1]
]);

console.log (math.inv (mat)); // Error: Can not calculate inverse, determinant is zero

This is probably a bug caused by #1114.

Sorry about that, I'll try to get it fixed tonight.

Fixed in the develop branch via #1124.

Thanks a lot for the quick fix Eric! The fix is applied now in v4.4.2
