[petsc-users] Question - read text file

[Marcelo Xavier Guterres]

Dear friends,

I need to read a matrix from a text file (txt).

This matrix has a high dimension (2000 X 2000) .

Example: date.txt - provision in the text file:

1 2 3 5
5 5 7 8
5 6 8 9


What's the proper way to perform the action?

thanks for help
