InvMat1(142): after a strange error message, average: 3,083s

I know the inverse were not displayed, but is it any good ?
I think it is better for a benchmark do double duty, timing and verifying.

Instead of display nothing (but timing), we could add this to InvMat1:

err := Mat1 - inv(inv(Mat1)) ;
print(dot(err, err)); // dot product, so just 1 (hopefully small) number
