FullMatrix::print_formatted() issue

[Vinayak Vijay]

Hello,

I am trying to print out a matrix to a file using the following commands:

std::ofstream file("mat.txt");

cell_matrix.print_formatted(file);

However, the matrix that is printed out to the file has some missing

entries, which are actually 0.

Can someone tell me how can i print the 0 entries as well?

Thanks

Vinayak

The manual page (assuming cell_matrix is a FullMatrix)

https://dealii.org/developer/doxygen/deal.II/classFullMatrix.html#abdd86a102fefa37a3916a612d8e329bd

says there is an option “zero_string”, may be set it to “0” and try it.

best
