Instance Constructors

  1. new CoordinateMatrix(entries: RDD[MatrixEntry])

    Alternative constructor leaving matrix dimensions to be determined automatically.

  2. new CoordinateMatrix(entries: RDD[MatrixEntry], nRows: Long, nCols: Long)

    entries

    matrix entries

    nRows

    number of rows. A non-positive value means unknown, and then the number of rows will be determined by the max row index plus one.

    nCols

    number of columns. A non-positive value means unknown, and then the number of columns will be determined by the max column index plus one.
