Helping to save matrix in txt file

Hi, i need some help.

I have a matrix calle NOS and it looks like this:

1 0 0 2.33356978125e-009 -1.59876343136e-009

2 3 3 5 3.65137983322323

Another one called BARRAS:

1 0 3 5 50.69 147.656878779

2 3 5 1 456.12 123.123214234

Variable NNOS = 2

And i want to save these matrix into a txt file but i need to put more information on it. My txt file should look like this:

DATE: 01/07/2011

NAME: My Name

Example: Example_number_1

Dados: Quantidade de nos: 2 (the number 2 comes from the value in variable NNOS)

No Inci Incj v rot (titles of each column)

1 0 0 2.33356978125e-009 -1.59876343136e-009

2 3 3 5 3.65137983322323

Barra i j L V M (titles of each column)

1 0 3 5 50.69 147.656878779

2 3 5 1 456.12 123.123214234
