SparseMatrix¶

class pyspark.mllib.linalg.SparseMatrix(numRows: int, numCols: int, colPtrs: Union[bytes, Iterable[int]], rowIndices: Union[bytes, Iterable[int]], values: Union[bytes, Iterable[float]], isTransposed: bool = False)¶

Sparse Matrix stored in CSC format.

Methods

`asML`()	Convert this matrix to the new mllib-local representation.
`toArray`()	Return an numpy.ndarray
`toDense`()

Methods Documentation

asML() → pyspark.ml.linalg.SparseMatrix ¶

Convert this matrix to the new mllib-local representation. This does NOT copy the data; it copies references.

Returns

pyspark.ml.linalg.SparseMatrix

toArray() → numpy.ndarray¶: Return an numpy.ndarray

toDense() → pyspark.mllib.linalg.DenseMatrix ¶
