SparseMatrix
Data Structure: Sparse Matrix whose implementation is modified from M4J
library
Compressed
Row Storage (CRS)
Compressed
Col Storage (CCS)
|
Class and Description |
---|
DenseMatrix
Data Structure: dense matrix
A big reason that we do not adopt original DenseMatrix from M4J libraray is because the latter using one-dimensional array to store data, which will often cause OutOfMemory exception due to the limit of maximum length of a one-dimensional Java array. |
DenseVector
Data Structure: dense vector
|
DiagMatrix
Data Structure: Diagonal Matrix
|
MatrixEntry
An entry of a matrix.
