C# 클래스 MyMediaLite.DataType.SparseBooleanMatrix

Sparse representation of a boolean matrix, using HashSets
Fast row-wise access is possible. Indexes are zero-based. If you need a more memory-efficient data structure, try SparseBooleanMatrixBinarySearch or SparseBooleanMatrixStatic.

메소드 설명
CreateMatrix ( int x, int y ) : IMatrix
GetEntriesByColumn ( int column_id ) : IList Takes O(N) worst-case time, where N is the number of rows, if the internal hash table can be queried in constant time.
GetEntriesByRow ( int row_id ) : IList
NumEntriesByColumn ( int column_id ) : int
NumEntriesByRow ( int row_id ) : int
Overlap ( IBooleanMatrix s ) : int

Get the overlap of two matrices, i.e. the number of true entries where they agree
RemoveColumn ( int y ) : void

Removes a column, and fills the gap by decrementing all occurrences of higher column IDs by one
Transpose ( ) : IMatrix

Get the transpose of the matrix, i.e. a matrix where rows and columns are interchanged
this ( int x ) : ICollection
this ( int x, int y ) : bool

Indexer to access the elements of the matrix
