Examples
Here are two examples of input files and the resulting matrices. On the right you can see the generated matrix both as a MatrixMarket file generated by matgen and as a Matview pciture.
The first example is a random sparse matrix and the second is a random sparse by row matrix. See docs page for more info on matrix types.
