Works well, thanks for sharing this! Also great that it contains enough comments to be understandable for others.

One little error is present in the file:
Line 56: 'u2dot = u;' contains a typo, therefore the u2dot isn't pre-allocated.

Dear Jose Antonio Abell Mena,
I download your Newmark Direct Integration file. I want to use that but how can i do that, i don't know? I have acceleration-time history. And i want displacement and velocity graphs. I'm new on matlab. Please help me. Thanks
