| Modifier and Type | Method and Description |
|---|---|
DoubleMatrix<String,String> |
read(InputStream stream,
int offset)
Read an entire sparse matrix from a stream (JW format).
|
DoubleMatrix<String,String> |
readFromAdjList(InputStream stream) |
DoubleMatrix<String,String> |
readFromAdjList(String fileName)
Read a sparse symmetric square matrix that is expressed as an adjacency list in a tab-delimited file:
item1 item2 weight
item1 item5 weight
IMPORTANT: By definition the resulting matrix is square and symmetric, even if the symmetric edges are not
explicitly listed.
|
DoubleMatrix<String,String> |
readOneRow(BufferedReader dis,
int offset)
Use this to read one row from a matrix (JW format).
