mtx file

Hi guys,

I have a vector represent a matrix, and now I'm trying to write it into a .mtx file, could anyone tell me how to do it?

Here is an example matrix: <1,4,5,3,2,1,4,5,6>

Many thanks

A for loop perhaps?

Code:

std::vector<int>::iterator it;
for ( it = vec.begin(); it != vec.end(); ++it )
   ofstream << (*it);
