DenseMatrix¶

class pyspark.ml.linalg.DenseMatrix(numRows: int, numCols: int, values: Union[bytes, Iterable[float]], isTransposed: bool = False)[source]¶

Column-major dense matrix.

Methods

`toArray`()	Return a `numpy.ndarray`
`toSparse`()	Convert to SparseMatrix

Methods Documentation

toArray() → numpy.ndarray[source]¶

Return a numpy.ndarray

Examples

>>> m = DenseMatrix(2, 2, range(4))
>>> m.toArray()
array([[ 0.,  2.],
       [ 1.,  3.]])
