Suppose there is a tensor of torch.FloatTensor x with size 3x4:
1.2045  2.4084  0.4001  1.1372
0.5596  1.5677  0.6219 -0.7954
1.3635 -1.2313 -0.5414 -1.8478
Is it possible to insert a tensor(e.g.,[ 0 0 0 0]) with size 1x4 into the second line?
The result should be:
1.2045  2.4084  0.4001  1.1372
0.0000  0.0000  0.0000  0.0000
0.5596  1.5677  0.6219 -0.7954
1.3635 -1.2313 -0.5414 -1.8478
