Input Matrices

We conducted our SpMV experiments for C, JavaScript and WebAssembly with 1,952 real-life examples of sparse matrices obtained from The SuiteSparse Matrix Collection (formerly the University of Florida Sparse Matrix Collection) at (https://sparse.tamu.edu). Please find the list of selected input matrices from the collection.
