BlockMatrix

Instance Constructors

new BlockMatrix(blocks: RDD[((Int, Int), Matrix)], rowsPerBlock: Int, colsPerBlock: Int)

Alternate constructor for BlockMatrix without the input of the number of rows and columns.
Alternate constructor for BlockMatrix without the input of the number of rows and columns.
blocks
The RDD of sub-matrix blocks ((blockRowIndex, blockColIndex), sub-matrix) that form this distributed matrix. If multiple blocks with the same index exist, the results for operations like add and multiply will be unpredictable.
rowsPerBlock
Number of rows that make up each block. The blocks forming the final rows are not required to have the given number of rows
colsPerBlock
Number of columns that make up each block. The blocks forming the final columns are not required to have the given number of columns

blocks
The RDD of sub-matrix blocks ((blockRowIndex, blockColIndex), sub-matrix) that form this distributed matrix. If multiple blocks with the same index exist, the results for operations like add and multiply will be unpredictable.
rowsPerBlock
Number of rows that make up each block. The blocks forming the final rows are not required to have the given number of rows
colsPerBlock
Number of columns that make up each block. The blocks forming the final columns are not required to have the given number of columns
nRows
Number of rows of this matrix. If the supplied value is less than or equal to zero, the number of rows will be calculated when numRows is invoked.
nCols
Number of columns of this matrix. If the supplied value is less than or equal to zero, the number of columns will be calculated when numCols is invoked.

def add(other: BlockMatrix): BlockMatrix

Adds two block matrices together.
Adds two block matrices together. The matrices must have the same size and matching rowsPerBlock and colsPerBlock values. If one of the blocks that are being added are instances of SparseMatrix, the resulting sub matrix will also be a SparseMatrix, even if it is being added to a DenseMatrix. If two dense matrices are added, the output will also be a DenseMatrix.

def multiply(other: BlockMatrix): BlockMatrix

Left multiplies this BlockMatrix to other, another BlockMatrix.
Left multiplies this BlockMatrix to other, another BlockMatrix. The colsPerBlock of this matrix must equal the rowsPerBlock of other. If other contains SparseMatrix, they will have to be converted to a DenseMatrix. The output BlockMatrix will only consist of blocks of DenseMatrix. This may cause some performance issues until support for multiplying two sparse matrices is added.
