SparseMatrix(int, int, Table<Integer, Integer, Double>, boolean) - Constructor for class librec.data.SparseMatrix
Deprecated.
I don't recommend to use this method as it (takes time and) is better to constructe the column structure at the time when you construct the row structure (of data table). This method is put here (as an example) to show how to construct column structure according to the data table.
