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

asML()[source]

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:
pyspark.ml.linalg.DenseMatrix
toArray()[source]

Return an numpy.ndarray

Examples

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

Convert to SparseMatrix
