DenseMatrix¶

class pyspark.mllib.linalg.DenseMatrix(numRows, numCols, values, isTransposed=False)[source]¶

Column-major dense matrix.

Methods

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

Methods Documentation

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

New in version 2.0.0.

Returns:

toArray()[source]¶

Return an numpy.ndarray

Examples

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