Dear Folks,
A bug report in cmetric made me notice that something is badly mess up with
matrix inversion when detout is set to true:
(%i1) ident(4)^^(-1);
[ 1 0 0 0 ]
[ ]
[ 0 1 0 0 ]
(%o1) [ ]
[ 0 0 1 0 ]
[ ]
[ 0 0 0 1 ]
(%i2) detout:true;
(%o2) true
(%i3) ident(4)^^(-1);
(%o3) [0, 1, 0, 0] [1, 0, 0, 0]
Not sure what happened here; the code works fine in 5.27.
