I have 2 questions about MatView.

1.    I would like to ask if the process below is possible.
When running in parallel, is it possible to make the matrix of the mpiaij
format into a txt file, output it, and read it again so that the entire
process has the same matrix?

2.    If possible, please let me know which function can be used to create
a txt file and how to read the txt file.
