I want to know what is the best way to load a matrix market format matrix into Sho's DoubleArray?
The matrix is pretty large (5,000 * 50,000) but however sparse.
I tried reading the file line by line and indexing the DoubleArray but it takes almost 3 hours, is there a better way?
Thanks in advance.
I use this on a 2 million by 10 million matrix with .6 billion nonzeroes
this.shoSparse = new ShoNS.Array.SparseDoubleArray(filename, ShoNS.Array.SparseFileFormat.MM, true, ShoNS.Array.SparseStorageFormat.CSR);
Takes about 20 minutes
