leftMultByMatrixTransposed
public static MatrixBlock leftMultByMatrixTransposed(CompressedMatrixBlock right, MatrixBlock left, MatrixBlock ret, int k)
Left multiplication with a CompressedMatrixBlock on the right following the equation: ret = t(left) %*% right- Parameters:
right- A CompressedMatrixBlock on the right side of the multiplication.left- A not transposed MatrixBlock.ret- The result output matrix, this allocation of the object can be used if appropriate, otherwise a new matrix Block is allocated to be returned. This argument can also be null.k- The number of threads allowed to be used- Returns:
- The result of the matrix multiplication

leftMultByMatrixTransposed
public static MatrixBlock leftMultByMatrixTransposed(CompressedMatrixBlock right, CompressedMatrixBlock left, MatrixBlock ret, int k)
Left multiplication with two CompressedMatrixBlock following the equation: ret = t(left) %*% right- Parameters:
right- A CompressedMatrixBlock on the right side of the multiplication.left- A not transposed CompressedMatrixBlock, but logically inside the function it is considered transposed.ret- The result output matrix, this allocation of the object can be used if appropriate, otherwise a new matrix Block is allocated to be returned. This argument can also be null.k- The number of threads allowed to be used- Returns:
- The result of the matrix multiplication

leftMultByMatrix
public static MatrixBlock leftMultByMatrix(CompressedMatrixBlock right, MatrixBlock left, MatrixBlock ret, int k)
Left multiplication with two CompressedMatrixBlock following the equation: ret = left %*% right- Parameters:
right- A CompressedMatrixBlock on the right side of the multiplication.left- A MatrixBlock on the left side of the equationret- The result output matrix, this allocation of the object can be used if appropriate, otherwise a new matrix Block is allocated to be returned. This argument can also be null.k- The number of threads allowed to be used- Returns:
- The result of the matrix multiplication
